We really enjoyed our stay in this traditional cave house in Megalochori. The village is so picturesque, like a Greek village dream. Megalochori was the most charming of all the places we visited while on Santorini. The location of the house is great, just a few steps from the main square, but quiet.
Like other reviewers have mentioned, it’s quite humid inside the cave. This bothered us a bit at night, and towels didn’t dry properly. Also the AC was broken. Don’t know if it would be less humid if it was working.
