It was a fun experience for my family to stay in the cave house (villa)! The cave house was stunning, room was spacious and clean, beds were comfortable. We were surprised that there were 2 bathrooms in the room, both were really clean and spacious as well. Our only complaint is about the shower - we had to run the water at least 3-4mins for it to be warm enough to take a shower. (We went on a cold/rainy day, so we really wanted to take a hot shower.) The villa is a 15 minute uphill walk to Fira town center, but the host was very kind to offer us a ride. We were also pleasantly surprised that breakfast was included. It was a good breakfast, both my teenagers were really happy with the food they provided. :)
Oh - if you feel like staying in to enjoy the room like we did, order takeout from the restaurant that the cave house recommended! The food was great and cheap!
