Nice, France There's a technical hub in the area and multiple universities, along with a lot of English-speaking expats. The weather is amazing and the food is fantastic. I'm from the SF Bay Area and I live here now. Best decision ever.
Nice is probably the last place I would go to in France. Bordeaux and Montpellier are much nicer places.
I completely agree that the night life and cultural scene is far better in student cities such as Bordeaux, Lyon, Nantes, Montpellier etc
