Excellent little gem. The location is perfect: it can't get more central (literally a few meters from Aristoteles Square), yet it's perfectly quiet.
The pictures and the description are accurate. There's a cozy living room, a well equipped kitchen, and a bedroom with one double and one single bed (the mattress and cushions were excellent!)
Both the bedroom and the living room have small balconies that face a rather unattractive internal space, and other than that, there are no windows in the flat. As we stayed during the winter that wasn't an issue.
Everything was perfectly clean, and we had everything we needed (and much more) in the flat. Giannis is a wonderful, friendly and dedicated host. Communication was great, too. Giannis checked us in, showed us the place, provided information and really cared. Much appreciated.
