23 years old girl looking for accomodation in Coimbra for the first semester

HI, I'm an italian girl from Milan and I'm looking for a room for the first semester. I would like find an appartment shared by students (better if non italians ;)) from september to february. I study at faculty of journalism, so i prefer central flat!!! It would be wonderful if my flat-mates were spanish or portuguese, for improving my language knowledge. I like travel, parties and i'm opened to new experiences!!! I arrive in coimbra on 25th august and i stay for few days in an hostel...so i need an accomodation as soon as possible ahaha=) help me guys!!
