The location is perfect. Right in the middle of the bay so you have an awesome view of the caldera and Fira.
There are 3 rooms next to each other but it feels private as they are well isolated and the terrasse is smartly devided. Not completely separated but it's anyway hard to have real privacy in Santorini even in top-notch hotels.
The Honeymoon suite has a private jacuzzi and this part of the terrasse has more sun during day time.
The room is lovely with a troglodyte feeling and very good value for money compare to other hotels in my opinion.
There is a great deal with Stella Rocca Mare hotel, just below, which has a killing view for you to enjoy your breakfast. And you can enjoy the pool for a minimum spend of 50 euros per head in drinks and food which is very reasonable as it's a small and pretty boutique hotel. Don't hesitate, book the room, you won't regret it!
