Third year bachelor student Business Administration, 21 year old and looking for accommodation (September to January) in Paris

My name is Maurice Russel and I am in my third year of Business Administration at the Free University in Amsterdam. I am coming in September to Paris so I am looking for an accomodation, I will leave in January. My hobbies are playing football, playing tennis and going out with friends.
A friend of mine from the same university is also coming to Paris this period, so it would be nice to find a two-bedroom-appartment. We prefer to find something around the center of Paris and our budget is 800 p.p.
