23 year old Norwegian physics student, looking for a room close to Rome centre

I'm doing a master's in physics. I wake up pretty early and go to bed before midnight. I don't spend too much time at home as I like being outside. Don't smoke, and I don't have guests over too often. I enjoy a clean home, so I always was whatever I used for cooking right after as a habit. I'm looking to rent somewhere close to The University of Sapienza, ideally towards the centre of the city if possible.
