Unbeatable view and location! Our only complaint was that it could be a little warm for sleeping in the upstairs bedroom. (AC unit is downstairs with just fans on top). Also as a note- you walk through a gift shop and up stairs to enter: would not recommend if you have any accessibility issues.
Host was very helpful and hot tub and langue chairs overlooking santorini were wonderful. You literally walk out into the middle of the city! Plenty of space for up to 4, would be tight with more.
