21 year old guy looking for accommodation in south of Paris

I am a 21 year old student from Granada, Spain with latin-american background (Mexico, Peru) currently living in London. I am coming to Paris to study for a year at the University ISIT and I am desperately looking for accommodation near the area of Arcueil or anywhere southern of Paris. I dont mind the type of  accommodation, shared flat or student halls is fine. My french is still not great so anyone english or spanish speaking would be ideal. Thank you!
