Looking for a room in a shared apartment - short term

Hi,
my name is Massimo, a 24-year-old Italian student from Mailand. I am planning on attending a German language class in Düsseldorf, at the Goethe Institut, in March and, therefore, I am currently looking for an accommodation where to stay during that month.
I am really looking for a shared apartment, since I'd rather not live on my own - there would be no point in going to Germany to study the language, otherwise!
I used to share my apartment with other guys and I enjoyed having my own rooms but I used to spend a lot of time with my roommates - even if that meant just a chilled night on the sofa chatting or watching a movie. I will be studying German and more than willing to do something in the late afternoon, at night or during the weekend, if you're up to it.
I will be graduating in Finance in Milan (Italy) in February and this is the reason I would like to move to Düsseldorf in March, to keep up with my German. I started studying this language one year ago and spending sometime in Germany can only improve it.
