My sister and me enjoyed our stay in Vasos well equiped apartement.
We felt really confortable during our five days in Athens. Even if Vaso couldn't welcome us personally, she was always reachable by phone and extremely helpful.
Exarchia is a nice corner with bars, restaurants and some little groceries, baceries. The metro station Victoria isn't far, from here you can easily reach the centre and sightseeing spots.
We heartful recommend Vasos airbnb.
