I stayed here over the Xmas holidays '22 and had a great time. The stairs look a bit grungy, and there is no elevator, but the apartment itself is great. Tasteful furniture, functional kitchen & washer dryer, comfortable bed and bright windows facing east on the kitchen/bedroom side for the morning sun. Very quiet, I didn't hear the neighbors at all.
I did pay extra for a parking space which wasn't really necessary since there was plenty of street parking, but it was a nice option to fall back onto.
The location is great, I used to live there a decade ago and it is always nice coming back. I'd recommend Café Jasmin (Augusten/Steinheilstrasse) for Kaffee&Kuchen and of course Steinheil for a great Schnitzel!
