This is a beautiful place to stay outside of the bustle of the other towns. It is just outside Oia, but close enough to walk. Very close to small groceries and restaurants. Very clean and cozy. Beautiful pool and the view is spectacular from both sides of the house. We expected it to be blazing hot, but there is a constant breeze that cools the house and the patio. The wind can really whip through there, so make sure that you are prepared. If your belongings blow out over the caldera, they will probably end up in Africa.
I would recommend getting a car. There is lots of parking and despite the crazy drivers, countless motorbikes / quads and pedestrians, it is well worth it for the convenience.
Aris is a great host and though we mostly just relaxed, he was very willing to make suggestions and help us. The cleaners for the home and pool were very friendly and kept everything sparkling.
Oia is a beautiful place and I am sure that the hotels there are exceptional, but with this villa, you get privacy, space and access to all the tourist attractions at a fraction of the price. We would go again in a heartbeat.
