First things first: the terrace is simply amazing! If there wouldn't be that many things to explore in Athens I would have also enjoyed to spend aaaaall the time there starring at the Akropolis which seems to be even closer than in the photos. Inside you don't have much space but it's also really not needed and everything is put in a very convenient way. The neighborhood itself is non-touristic but in walking distance to monastiraki and exarchia. Sokol was easy to reach and a very considerate host. I can definetely recommend staying with him.
