We utilized Blackberry twice on a recent trip 1) from Heathrow to Southampton hotel for overnight…read morestay; then 2) Southampton cruise terminal back to London proper. We were group of four with large size luggage. Both quotes & bookings are done via email. Once you receive a quote and are ready to pay there are several payment options offered. I used PayPal. Both pickups were easy. On day of pickup at LHR I got a text alert from Blackberry & the driver regarding where the car was and estimated arrival time. The driver met us at the suggested meeting place at LHR on time. Ditto Southampton cruise terminal pickup with a drop off at our London hotel. I'd booked with Blackberry if I'm ever in London again.

The drivers are awesome. They are really good conversationalists and helpful. You should read up about their test if you are not aware already. It seems impossible to pass! Sounds as hard as the grand sommelier test. Interesting tidbit I got on one of the trips on this visit. Turns out Sylvester Stallone had ridden the cab and was super nice and gracious. Loved hearing that!

They are identified by their license number in the upper left corner of their car. It is safe and reliable. The fare is clearly posted in the cab, no surprises. The drivers are knowledgeable and helpful Unlike Uber, you know who is driving if you need to. Uber can be anyone . Research is key when traveling as you want to be safe before you get in the car, in a strange city ! Support the hard work of these can drivers ! Uber May be cheaper, but you get peace of mind in a black cab!

However, with this particular mini cab firm, aside from being prompt to the minute, cabbie Ahmed gave me a virtuoso potted history of cab-driving in the capital including the variety of taxis that have been used and even tried to shed some light on the most ancient and obscure Hackney Carriage laws that are still on the statute book.

Coming back today with the M4 closure the driver took a circuitous route which avoided all the main detours and got us back much more quickly than we thought. Excellent.

The price is slightly higher (depending on how you travel) but if you consider waiting at the airport, long security lines, the wait time, it's a great value! This was the third time I have traveled with the train and it was clean, relaxing, we had breakfast and the train staff was very helpful if anything was needed. The waiting area and lounge can get a bit busy and there is limited seating. Depending on the arrival/departure schedule you may need to stand for a bit until seats open. But don't worry, you'll be at your destination very soon!

Incredibly rude staff. My husband forgot to take his phone out of his pocket. We felt it was a…read moresimple mistake, and while we understand that it poses an issue and it needed to go through screening, they acted like it was the worst thing he could have done. We were then berated for bringing luggage (normal sized bag plus carry-on). Then we were told more than once to get into the wrong line. One lady said that whatever she told us to do was correct (despite the signage and us questioning it), but the very next lady demanded to know who told us to go to her line, because it was incorrect. There was absolutely no need for the staff to be as rude as they were. You'd think they were all given notice this morning or something. We are not rude passengers. We try to make sure we're following the rules, we read signs before we ask questions, and we don't bring prohibited items, etc. We know it was nothing we did, nor was it anything we could have differently (apart from remembering to remove the phone from the pocket). They were treating everyone this way. I would rather brave CDG than do this again.

I have used this company lots over the past few years and they are always prompt, friendly and know exactly where they should be going. I know that should always be the case with taxis but in London it's a rare thing when it comes to mini cabs. Even when other companies have quoted me an hour to get to me these fellas have said 'no problem' and been there in 10 minutes. At the London Field Day festival, they helped me and my friend get home for a snip of the cost of the other places near Victoria Park and we only wait about 15 minutes. They are good if you are a single female traveling too. Thank you Diamond Taxis - you are my favorite!

Awful. I have been using Diamond cars for about 3 years. It…read moreis like any local minicab service, not especially friendly, but does their job. To be fair, they are good for local pick ups and drop offs. and actually good for going to airports. but their problem is the pick up from the airport plus the very arrogant attitude of some drivers, one of them definitely had some anger issue! Last week I booked a cab from abroad to be picked up from heathrow. when I arrive at the baggage reclaim, the cab driver calls me and says that he is going to take another 30 mins. I'm actually a patient person so I just said ok. I go out to the arrival and call the driver after 30 mins, he said that he will be late for another 5-6mins, and tells me to come to the 'drop off' area, which I had no idea where it was. I asked around dragging my suitcase, but no one seemed to know, so I waited outside the arrival near the taxi area for another 15 mins. still no sign of my cab turns out that the driver didn't have any credit on his phone and couldn't call me. very professional. I found out that he was on the departure level drop off. I had to go 3 floors up, he is still not there, takes him another 5 mins to appear in front of me. He did apologies but the tone of his voice is not especially sorry and just made excuses rather angrily. His driving was dangerous, rough and speeding way to fast. I expected some sort of discount, as I waited almost 1 HOUR after an 13 hour flight and used my mobile to call the driver about 5 times. but he refuses to give any discount. I called the office and they spoke to the driver, tells him to give me 2 POUNDS off. I thought they were joking but they were dead serious. I lost my energy to argue and just paid him 45 pounds that he did not deserve. When I turned away, I could hear him saying something rude to me. very disappointing as a loyal customer NEVER EVER AGAIN.
