23yr old girl, looking for Studentenheim/room in Berlin

Hi, I'm Caterina, I'm Italian and I'll be staying in Berlin from february to june where I'll do an internship in a language school. I'm looking for a place to stay for the first month (february), my ideal choice would have been a university dorm/student house/Studentenheim but it seems that people who aren't in Berlin strictly to study can't get a place in the queue. If you know any other solution (like private Studentenheim, student hostels or something) let me know ;) otherwise, I'd like to share a flat with other students, it'd be nice to get to know people. I'm an open person and I enjoy company, languages, cooking and being simply together with people (not all the time of course, I'm also a very responsible and quiet person when it's needed ;D ). let me know!
