Maria's place is excellent, we spent 2 nights at her place and everything was as described in the post. Maria communicated with me in a super fast way and answered all my questions in a matter of minutes. The place is about 5 min walking distance to the kamari beach and no more than 20-30 min driving distance to all other towns in santorini with excellent access to restaurants grocery stores and other services. We rented a car and this gave us a lot of flexibility to move around the island. I really recommend Maria's place to anyone planning to get an Airbnb in Santorini.
