Great place to stay, very close to the metro which is only two station away from the central part of Athens where the acropolis are. Definitely worth the price, the rooms are big enough and there is a good balcony. A good experience overall.
Slight problem is that noise insulation is not very well. One of the neighbors said she can hear anything from moving of chairs and talking. We have to be really careful not to make any loud sounds after 11pm (yes it is a local rule by the government, but we have to be a lot quite than we expected!)
