22 year old girl, student looking for accommodation in Munich

My name is Angela, I'm a 22 year old girl student in Barcelona. I'm going to do a 3 months-internship in Munich (September to December) and I'm looking for an accommodation if possible close to Ludwig-Maximilians University of Munich. 

I would prefer to have roommates, since I consider myself a very sociable person, although I'm respectful with each other's personal space. Although I don't mind if the offer is for a one person-apartment. I like sports, going out, reading, spending time with friends.
