Is there any good university in really small town of France?

Im french and you can go to Caen (Normandie); not too small not too big. Enjoy

Well, I did my two masters in Metz university (History and geography), in Lorraine, it's a smaller city although not too small, and I really enjoyed my time there. The major University is located on an island on the Moselle river, and between two courses, my friends and I could easily spend time in downtown Metz, browsing shops or talking in the cafés. In smaller cities, it's more easy to make friends, but you might dislike the weather here in Lorraine, it's much colder than Toulouse. (Don't chose Nancy, I spent a year there, the people were cold and I spent my time running between the 3 places where the lessons were given. Unpractical). Metz is a beautiful place!

Yes! You can go to Cannes, France - its much smaller, very laid back and beautiful. I attended College International de Cannes and was able to intern at the Cannes Film Festival in May.
