I loved my stay at Absolute Bliss!!
1) the service is absolutely perfect. The room is cleaned very thoroughly: I lost one of my earring on my first night and looked for it everywhere but couldn't find it. The next day, I see it magically appeared on the bed stand! They were able to find it during cleaning.
2) The location is so peaceful because the hotel is away from the busy spots like Oia and Fira, but still very convenient. It is fairly close to Fira (40 min taking the scenic walking path, 8 min by car). My favorite thing is that the balcony and the hot tub feel secluded. Not to mention the view is amazing, and you don't see other people in sight.
3) We came during November so many things are closed, but the hotel provided us with everything. In addition to a complimentary breakfast, they have a menu of food and wine to order from. The food are delivered to the room within 30min. The receptionist is open 24/7. It is clear they thoroughly thought what the guests might need, because they have a cute booklet that describes everything: from information about the room, service, where to visit on the island, etc.
Absolute Bliss is unlike a big luxurious hotel, but it is very special and you will miss it after you leave.
