20 year old British/Spanish student looking for accommodation in Bologna

I am a student participating in an exchange with L'Università di Bologna and am looking for accomodation for the coming year.I speak English, Spanish and French and am in the process of learning Italian. Currently studying History and the previously mentioned Italian. I would be either interested in a studio apartment or a relatively spacious room in a shared apartment, the location being as close to the hsitorical center as possible, if not within it. Like to find a healthy balance between my studies and social life and I am very keen to be spending the coming year in such a wonderful city.
