The apartment is in a fantastic location!! It's right next to the Acropolis, Acropolis Museum and metro. The street is lined with restaurants and is very lively at night, but you wouldn't know because you thankfully can't hear it from the apartment.
To the right is a nice common area where folks hang out (especially at night) and people play music and sing. Keep going down the road and there's a bunch of shops to check out.
After walking around half of Athens in a matter of 3 days, it was very convenient to have an apartment close to so many food choices. Area is safe and never felt threatened at any point.
Only thing to mention is the shower is probably not best suited for tall people. Other than that, I highly recommend this place and will definitely try to stay here again if I ever come back to Athens!!
