We choose the listing to be away from mainstream tourism and were very happy with the quiet beach just down some stairs that we had to ourselves for many hours, typically the only company would be one or two greek people stopping by in the late afternoon for a swim.
The view of the sea from the terrace is great and we enjoyed eating breakfast and some dinners there too.
You need a car to get around. Fira and Oia are both close and Pori is a good base to go there and explore or have dinner.
Nicholas recommended some nice restaurants to us and we also very much enjoyed the hike from Fira to Oia that he had suggested.
