The apartment is very convenient, a short distance from Petralona metro station, and a few metro stops from both central Athens and Piraeus. We found it easy to walk to almost everywhere we wanted to go in our short stay (which was good because of a sudden 24 hour transit strike!). There are a lot of good restaurants in the area. We had a problem with the code for entering the apartment but it was resolved very quickly. All in all an excellent stay!
