The cave house was charming, larger than we expected, and had amazing caldera views. Definitely a very cool, unique experience. The small, private jacuzzi tub on second floor above apartment was quite nice and the house's AC worked great. We appreciated that our host provided breakfast items (bread, lunch meat, cheese, Greek yogurt, orange juice), water, and bottle of white wine. Also provided basic toiletries including soap in kitchen and bathrooms and paper towels and toilet paper.
The house is located near base of Oia so lots of steps - 99 to be exact, we counted -- to get down from and back up to the main street. Owner/manager arranges porters to carry luggage both up and down. We rented a car from the airport, and appreciated the assistance in finding a place to park once we arrived in Oia. Main Street is loaded with shops and restaurants with beautiful views. At night neighbors in nearby cave houses can be loud but only an issue if outside in jacuzzi. Can’t hear them inside.
