The driver showed up late to pick us up, we had to walk very far through the airport and the parking garage to get to his car. Once we got to the parking garage we waited 25 min for the driver to figure out how to pay the parking fees. Overall, the driver was just not organized. I would not recommend this private arrival transfer. On the way back home we took the Gatwick Express train. It was faster, easier and cheaper.
The shuttle service was very accommodating to our many changes to the itenary. They were the first to let us know that our initial flight to Gatwick had been cancelled, and managed to picked us up from Heathrow on the rearranged flight. Although the journey was long and tiring, our driver was very nice to show us the various landmark buildings in London, and also the other must visit places in London. She was the most helpful as this was our first trip to London. By far the best Airport transfer the we had. Thanks!
