The apartment was in an ideal location for most tourist activities - incredibly near to the Acropolis and associated metro station so you can get around - meaning it's also very easy to reach the apartment from the airport via metro (one change of line, nine euro per person single).
For us, we preferred to travel to other neighborhoods in Athens as we found the local area a little too touristy, but that is to be expected so close to the Acropolis. There are plenty of shops, bars and places to eat nearby though.
We did experience some problems with the wifi during our stay and we were without wifi for the duration.
All in all, its a clean and cosy apartment in a good location for exploring Athens.
