Globalement everything was very top !
The place, the little attentions, the explanation, the communication, the advices, the clean area, the commodities... :-)
Only thing to know if you are looking for calm : the neighborhood is very lively, and they are bars playing music until 5am under the window.
So if you are here to rest it’s not the place during the weekend ! (I don’t know during the week) anyway, the location is super if you want to be at the very center of the wonderful Athenian culture & night life.
