This was an awesome find and such a cool/unique place - between the spacious jacuzzi with a sunrise view to the hills to the east, the cool cave bedroom, and the gorgeous bathroom, A/C, and the awesome hospitality and responsiveness of host Panos, I can firmly say this was and is one of the coolest places I've ever booked for lodging in my life.
Akrotiri is also a great city to stay in, being far less touristy than many other spots on the island. I enjoyed the peaceful serenity of the location of the Cave House, and feeling much like a local in Santorini.
I'll definitely be staying here again when I'm next in town.
