We used Welcome Pickups at Athens from the airport to our hotel which was close to Acropolis. Their service had four good points. One, the driver spoke English which was easy to listen for us, non-native English speaker. He spoke easy English and his pronunciation was clear. He seemed to be native speaker. Two, he prepared bottles of water and a fabric bag (which was printed "Welcome-Pick Ups":-) ). The bag did not look expensive but useful. Three,The taxi had USB socket and my partner used it during 40 minutes driving. It also had Wifi. At last, he played our country's BGM. It relaxed us. If I suggest an improvement for him, slower driving is much better. He drove fast that scared my partner a little bit.
