I really liked this place. The apartment was as pictured and had a terrific view. It is in a very iconic Santorini location, so you have to fight through a lot of tourists (during peak season) to get to the steps to take you down, but once you are there it felt private.
They arranged for our transport and a porter met us at the drop off place to help us with our bags. Then a nice woman, Catherine, came to give us an overview of the island and orient us to the cave house.
When I locked myself out, they responded in five minutes time and somewhere was there in 10.
Things to know: they weren't kidding about the steps and the kitchen is equipped for very basic things. If you have any intention of cooking, know that it took me 30 minutes to boil a pot of water!
All in all, lovely.
