My wife and I stayed in the apartment for 16 nights. It is very much as described in AIRBNB. It is very clean, actually it was cleaned twice when we were there, bed linens and towels were also changed twice.
It is well equipped for a long stay.
It is located us a very lively area, with several restaurants, cafés, bar. The U.Bahn is just in front of the building, and 3 Tram lines stop around the corner. You can reach many attractions in a short ride. or even walk to some of them. Transportation makes some noise at night, but the windows block most of it.
Communication was a bit of a problem before check in as I got some messages in Greek, however things were resolved before check in and we had no problems of communication during our stay. The place is just above Restaurant Asteria, and is managed by the restaurant owners/manager. Asteria personnel were very helpful and kind whenever we needed.
We enjoyed our stay very much.
