We had a wonderful time staying at Aida's flat. While not very large, it is very clean, efficient and quiet. The building itself contains quite a number of units but once you close the door to your own flat you hardly hear any of the neighbors. This is not a lived-in flat so it is more like a hotel.
The location is good and convenient to the subway station and a very easy walk to Marienplatz area. There are a number of good restos and bars within a 1 1/2 block radius. Best description for this area is "local neighborhood feel away from the touristy stuff."
Aida was a very gracious host. She was there to meet us and kept in touch with us throughout our stay to ensure everything was going smoothly. Will definitely stay here again.
