This place was perfect! We were greeted right when we arrived and had help carrying our bags to the room. You should know that, like much of Oia, you will have to climb several stairs to get to and from the room, but it is DEFINITELY worth it.
The room itself was very clean, and had an amazing view out on the caldera. It also has a semi-private plunge pool/hot tub with amazing views out over the water. The main room has two air conditioning units, so it stays nice and cool, along with a tea kettle and pod coffee maker. They also provided several bottles of water (you can't drink out of the tap).
The owners were very responsive and helped us find a buggy to rent to drive around the island, offered suggestions on places to eat and assisted with getting us a ride back to the port. I would highly recommend staying here if you're planning on spending some time in Oia!
