Oia is arguably one of the most beautiful places you'll ever see, and this cave house is like staying in a fairytale. Such a unique space, with nothing but the sea in front of you. It's lovely and cool, with nice touches of breakfast goodies and great communication. Pro tips: take advantage of the porters- especially on your arrival (not sure how we'd find it). The steps are a lot to handle if you're wrangling your luggage. It's a nominal fee and well worth it. Also- be careful when plugging in. I got an electric shock when connecting my phone to the outlet in the bedroom as it seems to not be a grounded outlet. The stay was wonderful overall, and it was difficult to walk up the stairs leaving it (even though I wasn't carrying my own luggage).
