The apartment is old but well cared, super nice host(smooth check-in),safe neighborhood, convenient location----About 12 minutes by bus to acropolis (20mins by foot),15mins to Syntegma (city center).
It's suitable for long & short term stay and as a single female traveller I felt safe.
P.S. Thank you Orfeas and sweet Maria Luisa for your hospitality----the local life tips and dining/culture map are helpful.
