The pictures here on Airbnb don't do this place enough justice - the location on the Oia caldera was absolutely perfect (and yes it's a prime sunset viewing spot on the roof deck, complete with beach/lounge chairs) and the place was super cozy. Everything was perfectly laid out and clean, the hot water was reliable, and the AC was in perfect condition. We didn't cook but the small pantry/kitchen seemed in order. During our time there (end of September), the weather was mild enough that we could just keep the windows open at night, which was great as we got to hear the sea breeze and listen to the waves. Not a sunrise viewing spot, but the early light lit the rest of the caldera (right out the front door) beautifully. Thanks Ioanna and Fotinos for having us! We hope we'll get to visit Santorini again.
