The cave house is absolutely fantastic! As many others have said it is close to the main walkway in Oia but far enough away to be quiet and secluded when you want to relax. The balcony is perfect for watching the sunrise and having an afternoon coffee. The bread and jam for breakfast each morning was spectacular. The bed was a bit uncomfortable but that was a minor thing. The overall stay was exactly what we needed and the restaurant that they own has great food and one of the better views in Santorini. I would highly recommend this place!
