We had an absolutely wonderful stay here! Maria told us that the cave house is 150 years old, and it was decorated with beautiful antique furniture and other knick knacks. It's such a unique place to stay, and the view is unreal. I would agree with other reviewers that the bed was pretty hard. The house is a bit secluded from the main street in Oia, providing some much-needed privacy from all the selfie-crazed tourists. Maria arranged our transportation to and from the airport, including a porter to carry our suitcases. Maria S. (a different Maria) booked a catamaran tour for us and even met us at the house to walk us to the tour meeting point. I've definitely never gotten that kind of service from any other air bnb and it made our stay seamless. We can't wait to come back to Santorini and stay here or at one of Maria's other properties!
