Good location. Is close to the center, you can take a bus right outside the building and It's 15 minutes walk to metro station. There is a supermarket next door. The neighborhood looks a bit old and kinda dirty but this is normal in all Athens apart from the center.
Pros: Wifi is good, kitchen is really well equipped, washing machine available, hair dryer, good AC, easy to move by bus. Close to lycabetus hill :) .
Cons: the stove is a bit higher than normal so it's a bit unusual. The apartment looks exactly like in the pictures but in reality looks kinda too hippie/bohemian for my taste.
