Possibly the best neighbourhood you could stay in Athens. Friends of mine, who live in Athens, told me that they regularly go to all the bars and restaurants in exactly that area. We had some very good restaurants and in general a very good time around there. Everything is walkable from here (Acropolis maybe 20mins). It can get a bit louder, but you can simply close the window and basically hear nothing anymore. Also, the cooling was working perfectly, so no problem sleeping with closed windows.
We had some very nice encounters with Dimitrios and his mother also, her bringing us breakfast or fruits, everything was very lovely and would surely recommend to come back.
