Stayed here for our honeymoon and was very impressed with the location in Oia and views of the sunset from our suite and balcony and private hot tub. The breakfasts were delicious. Finally, I thought the service was excellent from making reservations (boat trips, rental cars, dinners) for us to carrying our bags from the post office to our room.

I stayed at both Volcano Junior Villa and Aqua Deluxe Suite.
Volcano Junior Villa is just next to a road and you can feel the atmosphere of Oia. You can enjoy the best and direct sunset view of Oia. The Jacuzzi cannot view the direct sunset view as it is just next to the door and a wall separating the road. The room decoration is romantic, relax and with vacation feel.
Aqua Deluxe Suite is at another side and with more private area. The courtyard is not next to the room and you need to walk a few steps at the shared down stairs with another room. The courtyard view is good but the view is not wide.
After on site inspected the hotel, I personally recommend the Sunset Honeymoon Suite, then Marine Superior Suite and Volcano Junior Villa. A jacuzzi with sunset view is more useful than an indoor pool at Oia.

Stay here, treat your self you won't be disappointed. the sunset is like no other, the breakfast I still dream about and yes I love food. We stayed in the Eros suite and it was just perfect, the private pool and veranda where truely magical to take in the amaizing view. The staff could not do enough for you, 5 star experience all the way. Thank you Art Maisons Oia Castle for a memorable stay in Santorini.

Art Maisons hotel is in a view point where have excellent view of sunset. The hotel receptionists are very thoughtful, make a phone call to ask breakfast everyday. They give us a lot of tourism information and enthusiastic help.
