We really enjoyed staying at Andromahi's place. The view from the house and the position are just perfect. As you can tell by the pictues, you have to climb some stairs to get to the bed but that is not difficult at all. The shower is not too confortable only because it is not in any way divided from the rest of the toilet. We would definitely stay here again!
If you go to Santorini, follow Andromahi's advices, we were really satisfied with the activities and the beaches suggested!
