Great place to stay when in Athens :) The location of the apartment is good, the city center as well as many monuments are within a 15 minute walking distance and there are several busses and metro lines close by. It was perfectly clean and the host(s) were very helpful, flexible and friendly.
The only minor flaw is the shower, as it is in the middle of the bathroom without any shower curtains. Other than that, I would highly recommend this place :)
