The appartment of Zoe is perfectly located, if you are looking for a stay near to the centre and in a nice neighbourhoud. The centre of Athens is easilily to reach with the metro. If you wish to drink and eat something near to the appartment the place with the church near to the appartment is nice.
We did not cook and eat in the appartment, I think for 4 persons it would have been rather small. If you want a clean, simple place to stay and to eat out, this is a perfect and affordable appartment.
