Definitely the best experience when it comes to the level of hospitality and help from a host. My wife had a birthday during our stay and Stefania organised a birthday cake for her.
The apartment itself was new and clean, but it could use a few improvements like AC in every room. Most of the time AC was not an issue because Santorini is very windy, but the last days of July were pretty hot and the wind was getting weaker.
As for the equipment, apartment had everything we could possibly need. Santorini is a rather small island so if you have a car, it's always close to every important spot.
And if you love cats, there were also very friendly felines in the area.
