Alexia and George are excellent hosts. The apartment is great, very clean and the bathroom is huge, everything is perfect. We arrived on a Sunday afternoon and they waited for us with food because the stores were closed, it was lovely. There was also delicious homemade wine. They gave us a map with directions to visit Santorini.
The location is very good, good access to the rest of the island. It is very important to have/rent a car, there are places that cannot be accessed on foot. However, there are also beautiful places, like cliffs, to walk through.
