This is a great home for your stay in Santorini. The location is perfect, the house is charming, and we were visited daily on the patio by two sweet cats who made it feel even more like home.
Nicoletta helped us arrange taxi service to/from the airport (a shared van -- common in Santorini), and booked us on a wonderful catamaran tour of the caldera. Christina greeted us upon arrival at the town gate (Oia is pedestrian only), had arranged a porter for our bags, and helped us settle in, answering all our questions. Later, when we called about laundry service, she was quick to arrange this. For 10 euros, our clothes were collected by the housekeeper who comes daily (and does a great job), and returned the next day, folded and fresh-smelling.
Though my wife and I are tall and banged our heads occasionally on the upstairs ceiling, that only added to the quaintness of the place. I was happy I could stand tall in the shower, the best on our entire two week stay in Greece. Christina informed us that her great-grandfather was born in this house. What good fortune for them!
As my wife and I both run, we asked Christina where we might do so and she suggested getting up early to run the roads before traffic begins. This was a great tip, and allowed us to be at the Oia byzantine castle ruins for sunrise, a gorgeous surprise. We then found we worked up as much of a sweat doing two walking circuits of the nearby stairs to Amoudi Bay, so that became our exercise of choice.
The location is great, with convenient mini-markets just down the way (towards Amoudi Bay). We hit the larger markets to get groceries for the breakfasts we cooked in the mornings.
My only complaint is not at all about this wonderful airbnb. It's about Santorini itself. It's glutted with tourists, and has lost some of its authentic Greek charm. We went in the off-season (late September) but it was still crowded. That said, this felt like possibly the best place of all for our Santorini stay.
