22 years old boy searching for accommodation in Paris

I am an undergraduate greek student and I will attend some courses in Universite Paris Est Creteil - Val den Marne during the winter semester, due to erasmus exchange program. Any kind of accomodation is welcome. I am open minded, quiet and convenient person, who likes to hang out and meet new people but also really clean and careful about the house I stay in. I would prefer an accomodation in the center of Paris, but close to the university would be also great. I am smoker but there's no problem since I could smoke at the entrance of the building or at a balcony.
