One year as exchangestudent in Berlin

Hi! I have been searching for the opportunity to move to Berlin (into a hostfamily - i'm under 18) - plus a High School year. I've been looking and asking many exchangeorganisations about this, but they can't promise at all that it's going to be Berlin - and it just has to be!
Can you help me? I'd appreciate it so much!

- Maybe you are looking for a roommate? - Haha :)
Thank you in advance.

Hi, I want to study in Berlin.  Know anyone who is working at either Freie Universitat Berlin, or Humboldt-Universitat zu Berlin????
