My review about Notos Therme and Spa Hotel on Santorini is the following: This was the best hotel I've ever visited.

My review about Aegean Plaza Hotel on Santorini is the following: I stayed here with my parents and brother at the end of August for a week. The room itself and the bathroom were quite big and the room was cleaned daily. We also got clean towels everyday. The hotel was wondrous indeed with fascinating pool. The bar by the pool is nice even if the music is a little loud and the drinks are reasonably priced.
