Avis Car Rental. Do your homework before you pickup car at airport…read more Arrived at the airport only a few minutes wait and chose Avis as the office was in the airport itself.. Very friendly staff at both pickup and drop off. We paid £48 for 4 days hire thru British Airways. Of course, when you get to the airport, they try and sell you all the extra's but it was not a hard sell. I already expected this and politely declined. If you need a child booster cushion only, best to take one with you otherwise it is around 10 euro's per day. Just a word of warning when considering insurance. I am a very experienced driver, driving both coaches and buses in Europe. The driving in Lisbon is very chaotic and busy. The driving standards are not like in the UK. If you are not used to driving on the left hand side of the road, I would advise you to take out insurance before you go as it will be cheaper. We then went to the car park to pick up the car. VERY IMPORTANT. Check the car thoroughly. There was a lot of minor damage not listed on the sheet you have to sign. Luckily, I know what to look out for so made sure all the damage was properly listed on the document you sign. They are not looking to stitch you up, but spend a few extra minutes doing a proper inspection of your car as it will save you time (and money) later. In conclusion, would recommend but make sure to follow the points I have raised. You will be glad you did.

We had the worst experience ever with this rental. It took us hours to check in. We ended up buying…read moreinsurance (worst decision ever). When we walked over to pick up the car it was wedged between two pillars. We had to enter the back seat and pull the car totally out of the stall for us to get in and load our luggage. There was no one there to assist in anyway. The pick up spot was way to dark to take pictures of the vehicle. When we returned the vehicle it was chaotic to say the least. The people directing us didn't ask which car rental place so we had to circle the airport. Once we were there they took photos of the car. (Amazingly the lights were very bright as opposed to the dark pickup area). They found some light scratches smaller than a pen tip (which we believe were already there) What should have cost us less than $200 ended up costing us over $1,200. This was the worst experience we ever had with any car rentals! Big rip off. I will never use them or recommend them ever again.

Very Disappointing and Misleading Experience…read more I had a very disappointing experience with Sixt at Lisbon International Airport. I had already paid through Expedia for an electric car, but when I arrived, the agent made it sound extremely difficult and inconvenient to charge an electric vehicle. Based on what he told me, I decided to switch to another car. The agent then misled me about the additional cost. I was given the impression that the difference would be only about $140 for the entire 5-day rental. Later, I discovered that the actual charges were much higher than what I had been led to believe. Because of this, I returned the car the very next day. Even though I returned the car after only one day, I was still charged a significant amount of money. I have rented cars for many years from different rental companies, and I have never experienced this kind of misleading customer service. I strongly recommend carefully reviewing all charges and paperwork before accepting any vehicle or signing anything. Based on my experience, I will not rent from Sixt again and would advise others to consider other rental companies.

If you're looking for an affordable rental car in Portugal, DON'T SLEEP ON GUERIN…read more 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.

The worst car rental organization I have ever dealt with, and I travel internationally regularly…read more 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!

We tried asking about 5 airport employees where the Emerald Club was, no one knows. When we ask Enterprise employees where the EC is, they don't answer. They ask us to show us our membership and reservation then ask us to proceed to the 2nd floor. For Emerald Club members, you will have to hunt around for instructions - which says proceed outside to 2nd floor at Enterprise cabin. We walked upstairs, and outside around the airport. After half an hour, we realize that it was located on the 2nd floor in the rental car parking lot. Such an extensive headache for a service that should have taken the most 15 minutes in the US. We got our car an hour and 10 minutes after getting our luggage.

First, they tried to get us to upgrade and when we declined, they upgraded us anyway. The BMW required both hands and a hard push in order to shift into reverse, and it was very, very low to the ground. Upon return, an employee checked the car, finding no damage. Then the counter person came out and was on her hands and knees, crawling around the car in search of damage. She found a thumbnail scratch on a hubcap, and charged us 227 Euros! We are contesting this charge with our credit card. The investigator has yet to receive any information from Dollar, probably because they cannot show that the scratch repair cost 227 Euros. In the meantime, Dollar added a $20 charge from Madrid, and $3.50 from Oklahoma! There is no explanation whatsoever as to what they are for, and these charges are a mystery. We feel very ripped off, and advise people to stay away from the Lisbon Airport Dollar/Hertz company.
