looking for room in Paris from september until end of year

I am from Berlin and will come to Paris from September until the end of the year. I will be enrolled in the the second year of the mathematics master program at the University Paris-Didérot. I enjoy to play sports - I play lacrosse and do rock climbing / bouldering. I am a humble and tidy room mate who enjoys to cook whenever there is time. I am looking for a room in a shared appartement with room mates who like to spend time together. Or a studio or a room in a university dorm would be nice, as well. In general, a good social climate within the appartement is very important for me.
