Italian student looking for roommates for 6 weeks

I'm a 22 years old Italian student who wants to spend around 6 weeks in Berlin to study German at the Deutsch Akademie. I'm looking for a single room in a flat (possibly in a central area) to share with young people, wherever are they from. I'm a friendly and open minded girl and I hope to enjoy this experience as much as possible, even though I know that 6 weeks is a very brief period, and to meet many people from all over the world. I speak English, French, Spanish and a bit of German. I smoke cigarettes but it's not a problem if I cannot smoke in the house; I can cook, I'm clean and I love to party. I'm looking for roommates who can make me enjoy my month in Berlin and make me feel comfortable in such a big town.
