This was a very good place to stay for a month. The location is convenient: you can walk to the Acropolis area or you can take the metro which is close.
The apartment was very clean and well equipped, it had a great washing machine with a dryer. Big shower, very comfortable bed, air conditioners in each room. Ceiling fans with lights that can be turned on and off with remote control were a nice touch.
The Internet was reliable, but not fast for uploads, otherwise, it was good.
The area around is safe, on Saturdays, there is a large farmers market on a nearby street, also Lidl and another supermarket are close.
I would definitely recommend Nondo's place.
