This place was absolutely wonderful for our stay in Santorini - it is off of the beaten path and really gives you the experience of staying in a cave home. The town is adorable, and thankfully there are cute arrows painted on the narrow walkways that allowed us to find our way to the house when we did go into town. Oia is very walkable so you can see the sunset, and Fira is an easy taxi ride away. Otherwise this is a secluded escape from the hustle and bustle of the island.
Stamos met us when we arrived and was so helpful in getting us to the house and getting us acclimated. We availed ourselves of their kind offer to arrange for transfers to/from the ferry, and it was very nice not to have to worry about that.
Overall a very wonderful stay and amazing hosts.
(One small thing to be aware of if you are booking this location. One of the "rooms" is much smaller than the other two - it basically only has a bed and a bathroom. The other two rooms are much more spacious with a sitting room and larger cooking area in each. Just something to be aware of depending on the size of your group.)
