This huge building, which goes around the corner and thus is actually located on both Angerstraße and Gartenstraße, is "Gartenstr. 25".
The 25 is missing! Would be nice if it could be added. :-) 

The ground floor has several shops and businesses, some of which face (and have their entrance on) Angerstr. The upper storeys have residential apartments, to which the building entrance is on Gartenstr. (by the bike racks).
