We really enjoyed our stay at Pano's place. The area was generally quiet because there are no big streets close by. There is a lot to explore in the neighbourhood especially if you enjoy going where the locals hang-out.
The loft apartment was comfortable and everything worked as described. We felt very secure and didn't think twice about leaving our stuff behind while away during the day or evening. The Metro station is not far away but because we don't mind walking, we didn't use it except to go from/to the airport.
The main Athens attractions were less than 30 min away by foot and you can easily spend the day at the Archeological museum which is just next door.
Would highly recommend especially if you want to get the feeling of living like an Athenean.
