Atlantis Hotel surveys Fira, the capital of Thira, where the lost city of Atlantis may once have existed. The hotel has 25 rooms, most of them with balcony and breathtaking view to Santorini's caldera, volcanoes and the Aegean sea. The warm atmosphere of the bar, the terrace at breakfast, the swimming pool, and the kind and smiling staff, are all part of Atlantis.
