The cave house is a fantastic place to stay in Santorini. It is very spacious for 2 people and clean with everything you will need for a few days.
The house is located close to Karterados bus station where you can take the bus to travel around the island. There are also supermarkets, car,ATV rental shops and bars and cafes all within walking distance. It is also within walking distance to the main Thira bus station where you can go to Oia and the other beaches on the island.
We would highly recommend staying here, Lydia is also very helpful if you have any questions!
