This is a really nice cave house in a little village that doesn't allow cars/scooters. The house is large, has a nice kitchen, and gives you an authentic experience of staying in a real cave house. The village is quiet and as you walk the pathway inside the village you don't have to worry about being rundown by a car or scooter (a real danger in much of Santorini).
From the village it's about a 10-15 minute walk to Oia and the sights. It's a steep 5 minute walk to the closest bus stop. But beware, once you exit Finikia there aren't many sidewalks so you must walk along a busy road to get anywhere.
Our hosts were excellent. They met us when we arrived and helped to carry our suitcases along the sometimes steep pathway to the house. They gave us good advice of sights to see and bus schedules and were quick to respond to messages.
