Apartment with two bedrooms in the center of Rome.

Hello, my name is Fani and I am a masters' student in the university of Rome, Sapienza. I am looking for renting an apartment with a friend(female), in the center of Rome, or at least as closed to the center as possible. I am from Greece and she is from Italy. We need to find an apartment just for the two of us, so it is necessary that it has two separate bedrooms. We would like to rent the apartment at least for one year. Thank you.
