The location and view are close to unbeatable. Evi is an ambitious and intelligent host who will treat you like a friend and guide you through everything you can do on santorini. She literally wrote a book on the subject. She also left us with a phone to call her on any time night or day for concierge services, advice, or an emergency bailout. We used that phone a lot - I felt like James Bond with that thing; one call and Evi could make pretty much anything happen. She continued to act as our main go-to on the island, even after our stay with her had concluded.
Bonus points: fridge was stocked (even had a bottle of wine in it), Wifi was great (especially considering it's terrible every where else on the island), unit was cleaned daily and there was even a *laundry service*!
Overall would recommend it even go back myself. 10/10.
