Nice place and great hosts! You’ll definitely need a rental car to stay at this place, but it is very central to everything on the island, as Thira was only 10 mins away, Oia was 20 mins away, and Red Beach was around 25 mins. The place was a great size for a family of 4, and although we checked in after midnight, we were still welcomed with a fruit platter, some wine, beer and refreshments, and directions to everywhere on the island.
We received daily cleaning and linen replacements (first time I’ve seen this with an AirBnB), and the hosts allowed us to also leave our luggage after checkout as our flight left late at night.
The only thing to keep in mind is that I think the rooms may get cold in the winter (my wife found it slightly cool at night)), as it is sort of like a cave-like place (which the kids loved), and if you’re very sensitive to smell, you sort of get a pipe-cement smell from the bathroom and under the kitchen sink (I’m guessing a lot of places on Santorini will have this though).
Overall a great stay and we’d recommend if you need a spacious place, rather than a studio hotel.
