Cool place close to the subway. Also taxi is to be found at all times in front of the building.
Very clean and the guests very responsive and helpful via text messages.
The balcony is facing the sun during the whole day so it s extremely hot during summer.
The area seems a bit shady, although I do not know much about Athens. Also, the place is an hour away from any beach and the port, so if you intend to do more than visit the old city center, I would recommend a place closer to the sea.
