If you need a quick stay for a well enough reasonable price to quality ratio then it's fine enough. If you are on a vacation (foreigner) and are looking for a bit of a longer stay, then I'd suggest you look for alternatives. If you are a local, then probably you are used with the quality of this establishement. City as well as other tenents noises is something you should be used to, if you consider taking an apartment in the heart of city like Athens. If you are looking just for a place to crash after a day out, then it's perfectly fine - a roof over your head, clean sheets, kitchen if you feel like it in the morning.
Other than that the host is punctual, respectable, cleaner does a good job. Location is pretty good considering and considering the price it's an "all right" option.
