Rena is the best host you can hope for. She welcomed us even really late in the evening. She helped us with the transfer from the Airport to Oia by advising us a car rental company (Drossos) with her porters, and was always available if needed. She provided info about Santorini and even a breakfast for the first day. The Bateau Ivre is a beautiful flat where we spent a great time with an amazing view. However you have to be prepared for the big stairs, and that the bathroom is opened on the living room.
