A very new, modern and clean apartment building in the centre of Gkazi District. The Kerameikos Metro Station with direct link to the Airport is directly outside the door. The Acropolis, Monastiraki and Ermou shopping street are all within walking distance so that I did not need any public transport during my stay except from/to the Airport.
Check-in and Check-out was very easy and the hosts were very responsive to messages.
The only thing to be noted is, that the Gkazi district is one of THE nightlife spots of Athens. Although the windows when closed provided a good sound isolation you could still hear the night clubs around and sleeping with an open window was not possible due to the noise.
But overall I had a really nice stay in the apartment and recommend it to future guests.
