Spanish phD student looking for an accomodation in Rennes for 3 months

I a 28 years old spanish girl. I am looking for an studio or if not possible, a room in a shared apartment, for 3 months (15 may-15 august) near the center. I love travelling and meeting people and I am very easygoing. I am looking for a clean place located in an area close to the center and uni (campus of beaulieu) since I will be doing an internship there. I do not smoke and have no pets.
