A had a lovely experience staying at Dimitri's apartment.
It it located at a picturesque street in the most vibrant part of the city center. It allowed me to immerse myself in the Athens experience being in and out of the room as I pleased (very important given the hot climate of Athens).
Dimitris is a bright young man, extremely punctual and accommodating who has transformed the rooms of this old building into good taste, modern accomodations.
It is secure and easy to enter, just push first in and then out the heavy entrance door. That will make the trick. Very friendly and helpful neighbors.
I will definitely stay again.
