The location is great: very close to everything in Oia - walking distance to all shops and the sunset location.
We were met on arrival and Maria explained everything about the island for approx 30 mins, where to go, what to do, prices etc. which was very helpful. She even arranged a transfer for us from/to the airport!
The cave is a typical Santorini building with white walls and blue doors, an ideal stay. It's spacious inside - there were 4 of us staying with one sleeping on the sofa but she said it was comfortable. Maria even had UK adaptors for the sockets!
Very clean house - the cleaner came to clean every day, changing the sheets every other day.
Any time I asked Maria a question, she would respond within an hour - very easy to communicate with her.
Would highly recommend the house for a stay in Oia.
