Overall, this was a very good accommodation. I was here for a retreat, and was impressed by the way the hostel and staff accommodated our group. The food was fine. The views overlooking the Rhine were beautiful. There was plenty of space and different areas around the hostel to be in - the pool, a bar, a game room, large lobby area. My one complaint is that the shower area in the room did not have any kind of curtain or separate room. If you are in a room with people you don't know, this could definitely be an issue as there is no way to get into the shower without being visible to the entire room (especially a problem if people are frequently coming and going out of the room!)
I would stay here again, but make sure to be in a room with people I know!
