All I can say is Wow! This was our first stop on our honeymoon and we loved this place. The hot tub and view alone are worth the price of admission.
What really exceeded my expectations were the services included with the stay: the host arranged a ride from the airport (for a small fee), we were met with assistance to find the place and carry our luggage, the concierge (Catherine was very helpful: booked us reservations, arranged rides to the airport, and gave us many insider tips on the area), and also provided free breakfast and cleaning every morning. This really helped especially being our first time in Greece.
The location is an obvious selling point with the view, but we especially enjoyed the close proximity to the restaurants / cafes/ bars while also being tucked away (and elevated) to unwind in private. Be sure to wake up early for the sunrise (we thought it beat the famous Oia sunset).
Oia is a must if you plan to visit Santorini, and I would recommend this spot to anybody!
