We thoroughly enjoyed our stay at Simos' studio at Vathi beach in Sifnos. The room is clean and comfortable and has a large terrace with a nice view of the sea. It is also relatively private (the neighbors' terrace faces in a different direction so there is little contact with them) and has good shade thanks to some olive trees through which one sees the horses of a neighboring farm, which gives the place a rustic feel. Vathi is the nicest beach on Sifnos (calm water, nice sand, not crowded at all) and has a number of restaurants as well as two mini-markets if you want to cook. Everything is in walking distance. It is quite peaceful and relaxing to be there. Simos was wonderful -- he gave us tomatoes and eggs from his garden, brought us an additional table for the terrace and helped us to arrange taxis and a rental car.
