Georgios appartement is nice, cozy, clean and in a good general condition. He is friendly and busy, which means, you won't meet him that often when you are on a tourist scheudule (sleeping in and staying up late). Still, arrival and departure to and from the appartement is possible at every time of day, because the keys can be deposited in a key-box (at a location that will be disclosed to you after booking).
The room itself is clean, cozy as promised, has a balcony to the backside of the house and sufficient storage capacity for all the clothing you might want to bring.
The appartement is located around 5 minutes by foot from a metro station, which in turn is just one station away from the modern center of Athens around the parliament building.
A lot of good restaurants and bars are also in walking-distance. A pharmacy and an ATM are around the corner.
In short, a nice room with everything you need close by. A clear recommendation.
