21 year old girl student in international relations, looking for accomodation in Milano

My name is Pauline, I am French, I come from Nantes but I live in Paris since the start of september, I started a master in International Relations there. I am looking for a calm roommate, a student if possible, and friendly, it would be better for me have an Italian roommate as I am learning the italian language and as I will need it for my studies. If possible, I would like to find an accomodation close to "Universita Cattolica Del Sacro Cuore" (not more than 30 minutes far would be perfect). A shared flat is perfect but I really need a single room (this is not a condition).
