This cave house is my dream coming true. It's so beautiful and well equipped - located at the center of Oia next to the blue church(Oia is pretty small so location doesn't really matter tbh). We visited at end of March/beginning of April so overall not many tourists in town compare to summer. There were still some tourists taking pictures in front of it, but nothing crazy or disturbing.
The hot tub was a great plus for relaxation and we were surprised that there were two bathrooms. Unfortunately it was cloudy and windy when we went but the view was still very iconic from the balcony and I'm sure it will be more beautiful when there is sunset.
We will surely come back again if possible
