Our overall experience here was excellent! John was very responsive to messages before and throughout our stay and we were able to find the place easily thanks to his directions. The view was outstanding and the location in Oia couldn't have been better; we were initially worried that it would be noisy at night given it faces on to the main 'marble street', but it wasn't the case at all (I think most of the partying is done in Fira, but in any case Oia is where you really want to stay!). The room was clean and the access to the outside common areas was very nice at night. (The wifi was not strong while in our room, but out in the common areas it was fine.) I would recommend staying here to anyone coming to Santorini!
