My boyfriend and I just returned from the cave house and had a great time there. It is in a small neighbourhood of mainly locals, providing a quiet escape from the beaten tourist track, but is still fairly well-connected (15 min walk to buses in Mesaria, heading to the main city Fira where all other buses depart from; it's also easy to flag a cab from here). The flat is spacious, comfortable, and full of character, with a nice outdoor eating area. Finally, you could not ask for a kinder, more generous host than Katerina! Although we had some difficulty communicating in English, she offered to drive us places a number of times and left us food and gifts, while also respecting our privacy. She lives right next door which is convenient if you have any questions. Overall, we loved the house and would definitely recommend it, especially if you are renting a car or can approach the Santorini public transport system with a zen attitude (which you need pretty much anywhere on the island anyway!). Great for getting away from it all. Thank you, Katerina!
