Eirini's apartment was super centrally located and had an easy walking to all the main things and sights in downtown Athens. Short distance from few metro stations, grocery store, so many restaurants and bars one can't even count. Instructions to get to the apt were great and Eirini replied quickly.
Only minus with the central location would be a bar close by that played music late on Friday and Saturday night, the music kept us awake, so don't forget your earplugs unless you're out partying all night. Plenty of options for that as well.
Otherwise a perfect place to stay!
