It is charming, and Katerina is a kind and very gracious host. I'm sure the place would feel fine in most months beside August but does not have AC and sleeping can be difficult in those temperatures. The beds are, I guess "really firm" would be an accurate description. It is quite a ways from anything (public transport, any restaurant or grocery store) and so you really want a vehicle (ATV, Scooter) if you are staying here. If you want a very "local, real" experience this is great - if you want the most comfortable, luxury Santorini experience you want to look closer into Oia or Fira.
