This place was absolutely magical and the pictures do not really do it justice. The exterior is on a cliff that directly overlooks the sea, you are as close to the water as possible - the views are breathtaking.
Communication was fantastic. The place was spotless. The host was great. There is nothing to complain about. Just reserve this place!
Personally we booked a car during the stay as we found that really helpful to get around the island. Unfortunately Santorini is not very walkable. Just get a car (which the host will help you book) and enjoy the experience.
