This is a really great place to stay when visiting Athens, particularly for a solo/couple. The location is excellent - perfectly placed for Monastiraki and Plaka - and the roof terrace is truly special. We had it virtually to ourselves so we were able to gaze on the Acropolis at our leisure in the shade with a drink at hand - perfect!
Would particularly recommend the 6th floor apartment where we were for minimal street noise and aforementioned access to terrace.
