They couldn’t have been more amateur if they’d tried. Firstly, the site was almost impossible to find. It’s down an unlikely alleyway with no signs until you actually arrived. The office is tiny, no facilities, overflowing bins and generally dirty. Needless to say, they couldn’t find my booking until I showed it on my phone. It’s not a proper car park & you just have to drive around the tiny site looking for a space or dump the car in front of others. The transport to the airport is an old Galaxy, no help with the luggage. They also follow that annoying practice of charging all parties being transported (3 in our car) the £5 levied by Heathrow per vehicle. Per vehicle, which means they took £15 for our one visit. Rip off. Guy took no notice when I made this point to him. Return: waited 30 minutes in the rain before finally being picked up. Guy had no idea where our car was and we were told to wander around with the remote key until we found it, in the pouring rain! Basically, avoid if you possibly can.
