If you're looking for an affordable rental car in Portugal, DON'T SLEEP ON GUERIN. I was hesitant to book with them. My dad had a bad experience, and after reading review after review online, I almost thought about cancelling; however, I'm glad I gave them a chance. The airport pickup wasn't exactly a great first impression. Everything is done through a kiosk, which can be frustrating if you're not tech-savvy. I also felt a bit pressured to purchase their insurance, even after explaining that I'd already purchased coverage through Expedia. The vehicle pickup itself wasn't the smoothest experience either. That said, the Leiria location completely changed my opinion. The staff there were PHENOMENAL! Not only were they friendly and patient, they were genuinely helpful. I needed to extend my rental, and every employee took the time to walk me through the process and made sure everything was handled. They clearly explained my rental, insurance coverage, and all of my options. If the Leiria branch had its own Yelp page, it would easily earn five stars from me. They turned my experience around. read more

The worst car rental organization I have ever dealt with, and I travel internationally regularly. Not even sure where to begin... I went to their website, completed all the appropriate information, checked all the boxes and thought I was renting a car (2 months in advance). I got an auto response that it's not confirmed until I hear from them. There is a 9 hour time difference so I was asleep when they sent a message saying the car was unavailable. They suggested another car and I had two hours to confirm and enter my credit card or the reservation would automatically be canceled. Obviously, I missed the 2-hour window and there was no way to even get any more info about this unknown newly suggested car. I went through the entire process again, requested a car, stayed up super late waiting for them to open and grant me another 2-hour window. I received the email that my car had been approved and I had two hours to confirm it. I attempted to confirm, but I kept getting an error when inputting my credit card. It seemed to be an error on their end, but nevertheless, I tried several different credit cards (Citi, Chase, Amex, my card, my husband's card, etc.) and got the same message every time. I tried to refresh the screen, nothing worked.I spent the next 2 hours calling them at least 15 times (they should have been open according to all their info, but the automatic reply said they were closed), emailing them (at least 4 times), and trying everything in my power to get this reservation confirmed. I received absolutely zero response. I finally went to bed (3 hours before I had to wake up for work) and about 12 hours later, I received an email saying my reservation was canceled due to nonpayment. I still have not received any response to my emails asking for assistance, providing my credit card info, asking a question about the rental car, asking for more time... I got absolutely nothing! Initially, I was worried about the old bait and switch when they said the car I chose was not available. They automatically gave me a different/lesser car. But this was so much worse than that! read more

I rented a vehicle through Auto Europe and was later charged an additional €150 by Guérin, even though this charge should have been covered under my rental agreement. I contacted Guérin several times requesting a reimbursement, but they refused to resolve the issue. The lack of accountability and poor customer service were extremely frustrating. I expected the company to honor the rental agreement or, at a minimum, properly investigate the matter. Instead, I was left paying an unnecessary charge. Unfortunately, based on my experience, I cannot recommend Guérin. read more

Guerin (Lisbon Airport) charged me over 2,000 euros for the tiniest of dings in the windshield. If they fix it, then it would surely cost no more than 100 euros. Stay far far far away. read more

Guerin - Guerin's photo of the damage - Car Rental Near Me - Prior Velho, 20

See all

My $250 euro rental ended up close to $625.00. They upgraded us without permission, and it was to a lesser car than reserved. Then the extra charges started hitting my CC. They said to advise on return, I did, they did nothing and were extremely rude. These people are thieves. AVOID!!!! read more

Scammers! I'm angry I didn't look at all these reviews before booking a car at Lisbon Airport. I see many people have had similar experiences in that we were scammed for false damage charges! I guess they need to make more business this way because they suck terribly. I wrote to them and even included the local.police. Monica Sant'Anna from Guerin has yet to answer me in providing proof of photos before I took the car and the Police directed me to a website which is not valid. Hmmmm....DO NOT RENT FROM THIS COMPANY. SCAMMERS! read more

By far the worst experience with Guerin car rental in lesbian Portugal , where 1 star is actually too much. Dear people. If you end up at this company to pick up a rental car, try to get another Our rental car was vandalized and we were charged $830 in repairs broken window , We've spent 2 weeks trying every possible way to reach Guerin for the documentation our insurance needs, and they have not responded once. No customer service, no support, no resolution. Extremely disappointing--avoid this company at all costs. read more

Should've read the reviews before booking a rental here. If you're anything other than a Portuguese native, DO NOT USE THIS COMPANY! But if you think you're the exception then take photos and video of every inch of the car before you leave their lot. They tried to pin so much prior damage on us it's unreal... even something as small as a tiny rubber chip in the tire... THE TIRE! Avoid this place at all costs. read more

We have used Guerin for years in Portugal with no problems. This year we rented a car at Lisbon AirPort it was a hybrid, the car ran fine, no issues with that . When we turned it in, they told us one of the chargers were missing. We didn't use the plug in feature of the car at all, had no idea there was a charger in the rear , we weren't made aware of it when we picked up the car. Guerin kept our $500 deposit and refused to refund it. Than we received an invoice for an additional $245 Euros without explanation. We paid the car rental, insurance and tolls with our credit card as we had done in the past. read more

Total Rip-Off - Avoid at All Costs This company is a complete rip-off and will scam you if given the chance. I'm warning others so they don't go through the same frustrating and expensive experience I did. From the start, the service was misleading. I rented a car from the service in Lisbon and dropped it off in Porto. I paid one price online, including a one-way drop-off fee, only for the staff in both Lisbon and Porto to attempt to charge us twice more for the same fee. When I tried to address the issue, the customer service was dismissive, unhelpful, and at times even rude. They insisted we owed more money despite proof that we had already paid. In addition, they are now overcharging me €165 for a minor scratch on a hubcap. This scratch that was already there when we picked up the vehicle. It's ridiculous and feels like yet another way to squeeze extra money out of customers. The damage is purely cosmetic and clearly not new, yet they're treating it like a major repair. This kind of practice is unacceptable and speaks volumes about how this company operates. The whole experience with their customer service could have caused me to miss my flight. It's clear they count on customers being too tired or rushed to fight back. I've dealt with many rental companies in the past, and Guerin has easily been the worst. Save yourself the stress and take your business elsewhere. read more

WORST CAR RENTAL EXPERIENCE OF MY LIFE I rented a car to spend a day driving from Lisbon and Porto. At the time of booking (through National), the total price--including the one-way drop-off fee--was clearly confirmed. This was shown in the booking confirmation. However, at the Lisbon pick-up location, staff attempted to charge us a second time for the drop-off fee, and again at the Porto drop-off location--a third time. And again this information was specified in the rental agreement created before the booking and again the paperwork signed at the time of rental in Lisbon. To make matters worse, they are now charging me €165 for a minor scratch on a hubcap - a highly disproportionate amount- that was there when we picked up the car and written off by your team as negligible. The customer service was the worst I have ever experienced and the amount of time I wasted while your team took their sweet time during every portion of the process was unparalleled. I spent over an hour in each location dealing with these issues, dramatically changing our plans to the point where we missed lunch reservations in Lisbon and the metro stopped running in Porto forcing us to take a bus to our destination losing us another 2 hours of our time. I rented from National loyally for the past several years but this interaction with Guerin is making me change that. read more

Do NOT recommend! Paid extra for a GPS system for the time we were vacationing in portugal. Faulty equipment! GPS was old, outdated and did NOT work. We ended up using our phones the entire time and paying more to buy something to hook up our phones to in the car. We let Guerin know it was unfair to not be reimbursed for the equipment we paid extra for as it did not work and we could not use it! They said they understood and it would be taken care of. Then 2 MONTHS later a charge came BACK to our credit card for the GPS! Tried to argue it at that point with the credit card company as Guerin was being unethical. Guerin dumped a bunch of useless paperwork with the dates we "had possession" of the GPS (which was never the dispute... the rental was 3 hours away from where we were staying and we weren't going to waste a day driving 6 hours to drop it back off) and the charge remained on our credit card (i will be changing credit card companies as well. Capital One ruled in favor of the merchant despite the proof i had in emails about the system not working). DO NOT TRUST GUERIN at Lisboa airport. As other reviews have stated, they make up extra charges, are unethical, and clearly have zero concern for their customers, only how much money they can get away with. read more

I agree. I used them back in August 2024 and I paid for tolls and the car rental on 1 contract. They got their money for the car but now that I'm back on america and it's January 2025 they send me a ticket saying that my card was declined and therefore couldn't pay for my tolls. They got their money for the car though, ridiculous. Now I have to deal with paying for these tolls months later. They could have easily told me my card declined their payment for the tolls and I would've given them another card or simply approved the transaction. Had it been a payment for their rental im sure they would've reached out. Ridiculous. Don't use them! read more

I had a truly awful experience with GUERIN Rent a Car in Portugal and I want to warn others before they go through the same nightmare. I rented a car from GUERIN, drove responsibly, and unfortunately got into an accident -- which was caused by another driver who violated traffic rules and hit me. I immediately filed a police report and provided a full description to GUERIN, including everything needed for them to process the insurance claim. It was their responsibility to handle it with the other party's insurer. But instead of doing that, they: Kept my €600 deposit with no explanation; Refused to communicate transparently; Completely ignored my messages and attempts to get answers; And months later, they sent a debt collection agency demanding an additional €689 -- again, with no evidence that I was responsible for anything. I was shocked to receive a letter from a debt collector without any prior explanation or documentation from GUERIN. They never proved any fault, never showed me a damage report, and never justified why they are charging me money on top of keeping my deposit. I have now begun preparing legal action and will be reporting GUERIN to: The European Consumer Centre, The ODR platform, And other relevant authorities in Portugal and the EU. This is not just a case of poor customer service -- it's a serious example of financial abuse, lack of transparency, and unethical business behavior. GUERIN clearly shows no respect for their customers. If you value your peace of mind, do not rent from this company. read more

SCAM ARTISTS!!! IF I COULD GIVE NEGATIVE STARS I WOULD!!! Avoid at ALL costs, this business should be shut down as it is extorting customers, wish i looked up the reviews before ending up being charged $1800 for a rental car that was supposed to cost around $600. I booked the car in advance of my vacation (November 2024) to pick up from the airport in lisbon portugal. The total was $398 including accident insurance. At the airport i added my boyfriend as a driver to the agreement which was an additional $77 to the price. Fine. When i got to the counter the employee gave me a print out that said there was no damage on the vehicle and told me where in the garage it was located. They did not walk with me to get to the car. Upon getting to the vehicle, there was obvious signs of minor scratches and dents. I found the employee to ask what the deal was and try to get the damage documented so it wouldn't be an issue later. I wish i fought harder to have it documented at that moment. The employee came over to the vehicle and said oh i guess that is some damage, just take photos now and when you drop it off, show the employee that will receive the car. I asked to confirm that there would be an employee there since i would be dropping it off at 6am at the porto airport and i was told that there would definitely be someone there that early. THERE WASNT. After returning home I received an email that said i owed $1200 in damages, this is in addition to the $600 for the rental including accident insurance, toll fees, two drivers on the agreement. I was sent images of the damage which i had corresponding photos from the pick up. There was only one image that they sent me which did not have a time stamp, and i did not have a corresponding photos from the for. The damage in this photo was in a spot that we definitely would have seen, but we did not recall it - i dont think that this is a coincidence that it didnt have a time stamp. This company is absolutely awful and i wouldn't be surprised if this photo was from a different vehicle and they added it to get more money out of me. I am still waiting on a refund for all of the areas of damage that we preexisting and i had time stamped images of but they have completely ghosted me via email. I have called them as well and they just say oh someone will respond to your email by the end of the day, but they never do. They are benefiting from tourists being unable to contact them when they return home to a different country. DO NOT USE THIS COMPANY, THEY ARE AWFUL AND I AM SO FRUSTRATED THAT I DID NOT SEE THE NUMEROUS REVIEWS THAT ARE SIMILAR TO MINE BEFORE RENTING!!!!! I hope that no one else ends up being charged $1800 for something that should have been $600 and paying for damages that someone else caused/were falsified because these people don't care and are making money that they dont deserve from it! read more

Worst car rental in Faro! They will scam you out of hundreds of € in hidden fees, treat you like a dog and have no solutions other than more money or more charges! Will never use again in any city! The people at the agency were complete jerks, specially Rui Manuel Marçal, a disgrace of a human being that should not be dealing with the public. A coal mine would be a better place for him! read more

Waiting 2.5 hours to get a car because they don't have cars. Would give 0 stars if it was possible.

HORRIBLE EXPERIENCE FROM START TO FINISH. First they didn't have our pre-paid reservation when we landed in Portugal and we had to wait around the airport for about an hour or so for them to sort it out. Then we were on our way to return the car, it suddenly died as we were merging onto the highway. When we called the company, initially they didn't know we even picked up the car. We explained that the car suddenly died on us and that we were not able to fill the gas tank up. We were told "not to worry about it, this happens all the time and we would not be charged for it." We had a pre-paid cooking class that we were headed to that night but because we ended up being stranded on the highway after dark for about 2.5 hours waiting for a cab the rental company sent us, we missed that and just had to eat the $300+ cost. When we got back home, we noticed we were charged $1,050 by the company with ZERO explanation. Not only did they give us a shitty car, they ruined a day of our trip, and then slammed us with an outrageous and unexplained charge. All in all our $150 rental cost us almost $1,500. WOULD RECOMMEND AVOIDING THIS COMPANY. read more

I suspect most users will heed this warning too late - nobody, when renting a car from overseas, knows that Guerin means Enterprise and Alamo. Like me, they've used Enterprise and Alamo back home, trust them, and reserve a car with them when traveling. However, once at Lisbon airport, you'll find out that Guerin handles the rentals of Enterprise and Alamo, and they are an independent contractor. A fact that they point out in glee should anything go wrong. Which is what happened to our reservation. The rep Emilio asked us for a print out of our reservation. We showed it, with the confirmation number and all, on our phone. He said he couldn't find our reservation. We didn't print out a hard copy, that's why. I was curious what information should be on a piece of paper that's not on the confirmation email already, that could help him locate the reservation. He pointed to the sign stating that they are an independent contractor, so well, it's not his problem. Emilio suggested that we can pick up the car while they try to figure it out with Alamo (whose office would be closed for 3 days for a holiday weekend), but we thought it a bad idea to drive away without a clear contract. He said we can do a new rental, quoting a price 3 times as much as our original rate. As we booked the car via Expedia, we called Expedia, and thankfully the rep (who was located in Malaysia) tried her best to help us figure out this American reservation for a European car. After a long while, another rep at Guerin, Inez, was able to locate our reservation with ease. On to pick up our car! There are two employees at the counter. Each will help a customer, go through the paperwork, go to the lot to drive the car over, complete inspection and paperwork, before returning to the counter to help the next customer. You can imagine how fast the line moves... The car itself is fine, except that the cigarette lighter did not work, so we could not recharge our phones. A bad thing as we use them a lot for navigation etc. But we'd driven away already, tired, hungry and disappointed at a whole day's travel plan in ruins, and had no desire to make a u turn. read more

This message is to let the people know how to proceed when you rent a car with the Guerin rental car. They do not do a pre-check of your car. They use this method or to charge you when you return the car. They charge you with all kinds of things. Take pictures before taking the car. A lot of pictures. Tell them to sing your request . They charge more for any thing the car has . This is the way they make money. You are lured with lower initial rates. Then they screw you! read more

I made a reservation through Enterprise which is a partner with Guerin at the Lisbon Airport. I have averaged about 20 rentals a year over the past few years and this was hands down the worst company I have ever used. Do not use this rental partner. They charged me 260 euro for a small scratch on the wheel I did not make. Upon explaining it was preexisting they did not budge and said "you probably have insurance through your credit card, just use that" to my face. It seems as this is a very common practice with them, as they are looking to just pocket damage charges on top of their rental charges. Terrible customer service and I will be warning all friends and family to avoid them. They provide a terrible last impression of Portugal, and hope no one else has to deal with this dishonest company. They are criminals and I hope Enterprise stops associating with them in the future. read more

Sham car rental company at Lisbon Portugal airport. Rented car through national car rental company in states. They subbed to this local company. Upon returning car, my wife and I witnessed attendant who inspected the returned vehicle putting small scratch on hood of car with a sharp object concealed in his hand. He then informed us there would be an additional $350 charge to repair paint. We left without signing paperwork and immediately alerted national/enterprise where we have a corporate membership. Reversed the charges on credit card and sent to our attorney. Avoid this scam company at all costs. Never had this happen in 35 years of renting cars!! read more

Extra charges is their game. You'll end up paying extra for something or other. I was charged €49.00 for bringing the car from Portugal to Spain for 4 days even though the cost given by Discovercars.com, who I booked the car through, was €7.00 per day. I was then charged €100.00 for a small scratch to a wheel rim. Keep away! I'm hiring cars at Faro Airport for many years and I've never had these issues with the other companies I've dealt with. read more

For starter, it is very affordable. The waiting in line is extremely slow or are they just being very thorough? I sure hope that is the reason. However, it did feel like it was longer than it should have. Now, some run in diesel like the car I got. It's a standard tiny "cleo" made by Renault. It runs okay on flat surfaces and little hills but struggled on higher grounds. Now, I have to say some roads of Sintra are very narrow and very confusing but I managed well with the help of the navigation system. It wasn't efficient enough though that I have to advice you guys to have google within your reach. It will save you some time. Anyway, they offer very good insurance coverage for your entire rental if you choose it. I know I did because I never know the future. They bring the car with full gas, clean and ready to go but they also expect to get the car back filled with gas. They will clean the car again upon return for the next person. Returning process was much faster. I still recommend this place because it worked out very well for me in my opinion. You're welcome and Obrigada! read more

Scammers!!! AVOID Guerin if at all possible!!! They might appear to be cheap - but they have shoddy cars, horrid customer service and dubious practices. I booked through an online broker so didn't know which company I was hiring with - NEVER EVER again. We had the most awful experience with them in Faro and it took months of legal threats to get anywhere with them (basically they supplied us with a car which they knew was faulty and then it broke down mid-holiday). They represent Portugal and Portuguese people very badly indeed. Just awful! AVOID AVOID AVOID! read more

Worst car rental ever. Poor customer service, poor communicatiors and no system for dealing with clients. Truly a poor experience.

The moral of the story is that saving a few Euros sometime will do you more harm than good. I rented from a big name, Hertz, in Lisbon, it worked out good except that you have to expect all car rental companies will pressure you to buy insurance in addition to your own. Joining the rental companies' clubs helps because your profile is already on file. read more

Horrid service - spent 2hrs just to get the contract. Ended up costing $1500 for 2weeks with crap insurance read more

Somehow Guerin, Drive4less and Enterprise are all associated at the Lisboa airport kiosk, but conveniently disassociate from each other when it comes to policies. Buyer beware! I am still trying to eliminate the double charge on my credit card and was raped when I extended my rental by one day. Yes and the 3 hour queue at the airport was the beginning of this nightmare. My suggestion is to use Uber around the cities in Portugal and take the trains between cities. read more

Booked in Lisboa, Portugal. Febuary/2016. Alamo reserved on a local partnership, Guerin, who billed me on U$ 105 for 15 minutes of delay on drop off. I tried a solution with alamo, who wrote me back that´s everything all right on this over rate. read more
