Portuguese 21 year old girl, looking for a double bedroom in Rome, near Piazza di Bologna

Hi! I'm a student from de University of Coimbra, Portugal, and I'm going to Rome in September. Therefore, I'm searching for a room in the center of the city, or the "student region" of the city. I heard Piazza di Bologna is a good place! I also would love to share the appartment with another erasmus students from other countries :) I'm going to Roma Tre university but I would like to live near the center, where the magic happens :) (but near a metro station for my transportation)

I am looking for a double room (for me and my friend) under 400€, with bills included. 

If you know anything please contact :)

Ciao!
