20 year old boy, looking for accommodation in Rome for 3 months

I have just move to Rome for an internship for my university. I am studying in Amsterdam and in Rome I will be working as a kitchen trainee in Hotel de Russie.

I am looking for a nice room not too far from the center. I would love to share an apartment with openminded people but I also like some privasy and that is the reason I am looking for a not shared room.
