18 year old boy, looking to find an accommodation in Nantes.

I will be studying at the université de nantes from january to may. I want to find a roommate, or accomodation for while I'm there to help keep the costs low, and to also make friends in the city! 18 may seem on the younger side, but I'm quite mature and I'd make a great roommate. I'm not very messy, I like to keep my things clean and orginized, and I'm not very picky about who I room with.
