Hello from Bulgaria!

Hi Ivan,
You can try these links, however in Italian language.
You can find some rooms in local announce made from the italian students in the "campus".
In Milano rent are very expensive.

www.studenti.it/torino/
affittistudenti.studenti.it/

Try to find "posto letto torino/milano per studente" - it means bed for sudent or "camera per studente milano/torino" - it means room for student.

Excuse for my English
