Anastasis' place has the most fantastic view in Thira, I would totally recommend it if you are going to Greece to watch beautiful sunsets and relax. Antonios (the actual host) is an amazing guy! He was waiting for me when I arrived at the house, was in constant communication, and was always willing to help with things like ordering food, recommending restaurants, or booking a taxi. Couple of things to consider: (i) The house is very basic (you are paying for the view and the private pool); (ii) Kitchen appliances could've been cleaner (we had to wash them before we used them); (iii) Bring comfortable shoes if you want to walk to Thira, it's a 20 minute uphill walk, but the views are amazing, and; (iv) Considered renting a car - booking a taxi is very expensive, a round trip to Thira (8 minute drive) can cost you up to 40 or 50 euros, and a roundtrip to Oia it will cost you 70 euros!
