This is an amazing place to stay! The pool is wonderful, the guest house is nice and quaint, and Margarita was incredibly helpful, not only in getting us checked in, but in arranging transportation for us and having information for anything we needed. It's right down the road from the main center in Oía, so it's easy access to shops and sights.
The only constructive criticism we would have is the upstairs gets hot since the AC doesn't reach it, but the windows open for a nice breeze. A fan might be helpful up there as well as a curtain on the door to the upstairs porch to block the sun from heating everything up. The nighbors also had loud dogs, though I'm not sure there's much you can do about that.
All in all, this was an amazing find and well worth the money. We would definitely stay here again!
