It was so lovely at this place in Santorini! Not only are Nicolas and Kinga the kindest people, very helpful and caring, who live next door, but also is the house itself (an old cave right by the ocean) just an absolute retreat for everyone that wants to get away from all the hassle. It is so quiet and beautifully overlooking the ocean when you walk out of the room. Next to you is another room for guests, but the ones we met were lovely too and great company! The Kitchen and bathroom has everything you need. There is no air con, but Nikolas was so kind to help us out with a fan! That definitely helps.
I can really described the atmosphere at the place but it just slows you down and is really peaceful. The location is a bit out but as you should rent a vehicle anyway you're flexible. We didn't mind that it was down the hill, a little ride away from Fira. We were able to get anywhere on the island with our quad!
This place is just lovely and I can only recommend if you are not looking for the overcrowded tourist spots but peace and quiet.
Also ask Nikolas for places to go and restaurants! Great recommendations!
