Demetris is great at quick communication and the check-in/check-out was very easy. The apartment was clean and comfortable. It is an easy 6-minute walk (flat, no major streets to cross) from the Kerameikos metro station, which is on the metro line that goes all the way to the airport (a trip of approximately 42 minutes). We had no problem walking, or riding the metro, to all of the sights of Athens from this location.
