I was really pleased with this service. The car turned up before the time I had booked although I didn't know it was there! Make sure you have your phone at hand as they will ring you to say they have arrived :) as a bonus, I ordered a Sedan but got an SUV :) the details say that gratuities are included but we still tipped. You get so used to tipping that it feels wrong not to.
Booking the car took the hassle out of queuing for taxi's, driver was very friendly and full of useful advice. Would definitely recommend and use this service again
Driver was on time and very courteous. The only negative was that he dropped us off at the wrong terminal at the airport. Luckily we had plenty of time to get to the correct terminal. I would just expect he and his company to know better seeing he had my flight and airline information.
