Great location - conveniently located in front of the bus so there's easy access to Fira and Oia if taking that route; if walking it is right across the street from the caldera path. Fred and Olga were fantastic hosts - Fred is very knowledgeable about the area and is happy to converse with you on a diverse range of topics; they will also go out of their way to help you to arrange transportation and activities, and in a pinch they'll give you a ride too.
Great hosts who make you feel taken care of. The space is clean, cozy, and has an amazing sunrise view. Depending on which rooms/apartments you book, they differ in size. This room is definitely on the smaller side, but let's be real: you're not in Santorini to spend that much time in your room.
