20 year old student looking for accommodation for the first term

I'm a Spanish, French and Portuguese student from London looking for a flatshare for the Autumn term at Pau university, I am currently working as an au pair in St Tropez. Would preferbly like to live with French speakers (to improve my French) but am pretty happy with anyone. I'm a average, pretty laid back person and just want to make the most out of this term abroad.  Am happy to move into a ready made accommodation or create a group and find somewhere together
