I am in exactly the same position as you! I don't want to stay in the halls and there is nobody from my year going there either. I am studying for the full year September - May, hoping to move over there at the end of August to settle in etc. I am hoping to get somewhere in the town centre, the university is pretty far out and not particularly pretty I hear... Also I have been told most students cycle to the campus or get the bus which has an efficient service running from town. Could definitely use some help finding somewhere to live and someone to live with though!
On another note, have you had much correspondance from the university, I have only had one email and I am so confused about what to do next. Is there some sort of online registration? And where and when do we pick our modules?!
So much to worry about. I am going to be looking properly online for flats in Perpignan after my exams (finish at the end of this month) hopefully we can help each other out
I look forward to hearing from you!
