The location is THE BEST! It is centrally located at the lively part of Oia. The view is spectacular. We are also very happy with the cave house. This is one of the few original cave houses. We were told that it used to be part of a large cave house that belonged to a ship captain.
The concierge service was unexpected, and we found it very useful to help plan our stay in Santorini. Eleni was great. She was very efficient in helping us book a boat tour and a car rental last minute. She even waited with us by a parking lot to make sure we got onto the right bus for our tour (which we appreciate because there was another couple go onto our bus and it was the wrong tour), and gave us beach towels to use for the day.
Maria has a great team to provide excellent service for her airbnb guests, which I think she should have advertised it! This is beyond my expectation. The porter service they provide is necessary and reliable. It is almost impossible to find your way to the cave house on your own.
Overall we are very happy with the stay, and would recommend it to anyone.
