Since the Soccer league season is over when you are there, you should look up if there are other interesting sports events to that time. Visiting one of the relatively nice big stadiums (Munich, Gelsenkirchen, Dortmund) can be an event.
History can be a big point in nearly every big city but Berlin has a very special attitude because of the more recent german history. Tripadvisor may have some good ideas.
