Belgium girl looking for a place to stay during winter semester

Hi! I'm Polly from Ghent, Belgium, i'm 20 years old and i'm going on Erasmus to Leipzig next week(!!). Unfortunately the university dorms were full, so i'm searching for an alternative. I study communication sciences, my hobby's are swimming, music, hanging out with friends and theatre. I don't really mind where to stay, i prefer a place with other people so we can cook or hang out together but i'm not too picky :)
