Of the 9 different places - mixture of hotels, pensions and bnbs - that we stayed on our trip to Greece, this was in the top 2. Very clean, very comfortable bed, and a great view of the island caldera. There were plentiful choices for breakfast which was delivered to our suite every morning. There was reception/concierge on site for much of the day which was very convenient.
Note that you can *not* see the famous Santorini sunset from this location, despite at least one prominent guidebook suggesting it's visible from anywhere on the caldera. You will need to drive a few minutes in order to get a view of that. I would highly recommend renting a car if you are going to stay in this location, you'll be about a 15minute drive from the port or a 20 minute drive from Fira.
This is a relatively secluded area. There are places to eat within a quick driving distance but would be a bit of a hike on foot. There is also a grocery and a very good bakery just a bit down the road as well.
