If you're looking for an experience in one of the cave houses of Oia, we recommend this place! Maria and Eleni were very helpful in arranging a taxi to and from the airport, as well as helping with restaurant reservations etc. Very responsive to our needs. The house was also lovely - we are a family of five adults, and we fit very comfortably inside. It's a short walk away from the main street, up and down a few short flights of stairs, with a nice view of the sea and a lovely jacuzzi. There is a loft bed and small toilet on the second floor of the house, just note that there is no portable air conditioning there, but it's not a problem since the cave itself is quite cool even in the heat of the day.
