We reserved a car through Taxicode several days before our trip, and they cancelled as we were about to board our flight :( I had to scramble to find someone else with short notice and London-Heathrow Taxi came to the rescue. Our driver, Alberto, was lovely and our trip to our hotel from Heathrow was safe. Coordinating pick up locations at Heathrow airport can be a little frustrating as there's no designated place to go, but Alberto's communication was consistant in letting us know where he was. Thank you Albert - great meeting you! and thank you London Heathrow Taxi for helping us.
