Our stay at Grigorios and Marianne's villa was excellent. They were very accommodating with local tips and rides to/from the airport and port. The house itself was beautiful and a very traditional Greek style, which we appreciated. The only downside was that the hot tub was not hot. We would have loved to relax in there at night.
Very convenient location in Fira, walking distance to many bars and restaurants and close to the bus which takes you across the island. Overall an easy 5 stars. Would love to return some day!
