I would say do a lot of site seeing: historic spots like the Holocaust memorial, checkpoint Charlie , Berlin Wall, etc. I am 21 and the night life in Berlin is awesome but still a lot to do for younger individuals; just tour the city and eat se good food and learn a thing or two. It's a fairly cheap city compared to Munich and Hamburg. almost 5 years ago
The Natural History Museum was incredible and is PERFECT for children. This is a must see.
