We loved our stay at Aqua & Terra Cave Houses. Our host, Artemia, was fantastic. She answered my many questions in advance, arranged for a taxi to pick us up, and then met our taxi so we found our way to the house easily in the twisty streets of Oia. Artemia greeted us with a glass of wine, which was a lovely touch. She gave us a map, made some great recommendations for things to do and places to go, and was available for questions throughout our stay. The apartment was absolutely spotless, and the pictures are accurate. The kitchen was small but very well equipped, and had everything we needed including some butter, milk, cheese that Artemia had for us. I prefer a soft bed so found the bed a bit hard (like all European beds) but that's a personal preference not an issue with the apartment. I was a bit worried about the 2 apartments sharing 2 patios, but we literally saw the other guests only once and there was plenty of room for both groups with lots of space and privacy. The view from the deck was beyond spectacular - we spent a lot of time having a glass of wine and enjoying the view. In short, I'd definitely book this place again. It's not the cheapest option but was WELL worth it.
