26 year old student looking for accommodation during my stay in Milan for an internship

I will be doing an internship at Polimi for a couple of months and I'm looking for a comfertable room in a shared appartment, with roommates who like to hang out! Preferably close to the university or close to the metro line 2. 

A little bit about me: I'm a 26 year old student from the Technical University in Delft. As I said I will be doing and internship for the next months at the Politecnico di Milano where i will be working in the Medical Robotics section. My favourite activities include visiting festivals all over the world, sports, film and music (ranging from hiphop to electronic music). I consider myself a sociable guy, i spent a couple of months travelling by my own in South-East Asia, and i enjoy going out with friends as much as i can.
