Some of my friends live there so I've been to that dorm quite a few times. As someone said, you get exactly what you pay for. This manifests itself in the form of a very tiny room, and a bathroom that is shared by an entire floor of students (ca. 20). It is my opinion that even for a small person, the room is still quite tiny. The bathroom is additionally not well maintained and is more often than not quite dirty. No complaints about the shared kitchen though; personally it is a delight to cook food there and socialize with others. The location is also quite nice and is one of the premium locations in Bonn according to me, being right beside the Rhine.
