The Bluedome Cavehouse is simply the BEST villa in Santorini. Go ahead and book this place right now! Literally, look no further, stop reading this and book it! :) Our host, Petros, is the most hospitable AirBNB host I have ever experienced. He arranged our transfer to and from the airport, greeted us upon our arrival, made dinner reservations each night and had wonderful recommendations for daily activities. We were also pleasantly surprised with a bottle of wine and other breakfast foods. The view from the villa is unreal - I still can't believe we stayed there!
There are lots of steps to get down to the villa, so make sure you exercise a little beforehand :) We were very thankful that they helped us with our luggage!
Also, (just to note) there is a little old woman who will probably yell at you until she realizes you are staying at the villa. She yelled quite a bit when we were there at anyone who tried to sneak down to take pictures.
We are so thankful to have had the opportunity to stay here! We wish we were still there!
