Everything was fine. George was very kind and and picked up to the bus station, even if we were very late on the schedule. The next day he took me to Fira to the street of the rental vehicles in order for me to get one. And Alexia gave us a lot of sweet greek tomatoes and cucumber that were perfect to make a great salad. The apartment is like the description, very clean with a great shower and air conditioning and WiFi perfectly working. 15 minutes to the beach by foot, beach who provides free umbrellas and hot shower.
As other people said, the place is a little apart from the “movida” of Santorini and it’s absolutely necessary to have a vehicle in order to visit the other part of the island.
As I said: great hosts and great place. Nothing to complain.
