We had a great experience with Fanis and Tina, they were really responsive and have great support staff (housekeeping, porter, concierge). We started out at the Marble Sun in Oia, but because of construction next door (we were visiting in March when everyone is doing a lot of prep for the high season, something to keep in mind), which created a lot of noise and dust, they moved us to the Big Blue Villa nearby, which was lovely. The location in Oia is fantastic—everything is a stunning view, which made the hike up and down the steep stairs enjoyable! We rented a car through Katherine, the concierge, which was dropped off near the post office in town for an easy pick-up. Everything was made easy by Fanis and Tina and we really appreciated that!
