Exchange student looking for an economic shared flat in Karlsruhe

I'm an International Relations student from Mexico. I'm attending Karlshochschule IU this fall semester (sept-feb), and I'm looking for accomodation in a flat with roomates! I'm friendly and pretty chill. I like to party, but I don't have a problem with hang out calmly. I like to travel, learn new languages, stay at home and watch movies on my free time (but I doubt, and I hope, I won't do much of that on this semester abroad :D) I smoke but I can stand not smoking indoors... I love to get to know people from cultures different than mine. I don't mind sharing flat with male roomates.
