I think it's the best place to stay in Athens. But, haven't a good Internet connection (both as Wifi, as 4g): low speed and often disappears. For me was hard to work remotely. Still, good pluses:
+ location: near a subway, grocery, and cafes, but still quiet.
+ all the necessary appliances and utensils for a comfortable life.
+ balcony
+ comfortable couch and bed
