21 years old french engineer student from Paris looking for acommodation in Rome

I am a 21 years old french engineer student from Paris in my last year doing an internship in Frascatti at ESA. I need to find an acommodation in Rome preferably near Termini station where I can take the train to Frascatti, from the 27th of February up until end of July.

I am looking for a room in a shared flat with other active students.

I have already been a few times to italy before, but never to Rome. I have already done shared housings for other internships before in France and have kept a very good memory of it.
