Wonderful hotel with great view over the caldera. The staff is exceptionally friendly and nice, the rooms are clean and comfortable, we enjoyed several afternoons by the pool on the sunbeds and loved it.
Some reviews here say it's a bit remote and that's true. But in Santorini you always need a vehicle to get around, Imerovigli is about 20 min walk away with some shops and restaurants.
The breakfast could have had some more variety, Wifi works very badly in the rooms downstairs but that's only little things really.
We had one of the rooms downstairs with a jacuzzy outside and great views, unfortunately we could not really enjoy it much during the day as there was a family in the room next to us with little children. Of course, children are children but the hotel should maybe think about making the downstairs area with jacuzzys adults only as it would have been nice to enjoy a coffee down there without children screaming in the jacuzzy next to us. Of course the children are not to be blamed, they were lovely.
