avoid automatic redirection based on the browser language as it's confusing for Google.
Google place will be a problem as you need to have a branch address in each country you target.
In my opinion subfolders are easier to manage and Google accept domain.com/fr/index.html for instance as long as your targeted audience in the webmaster tool is France.
If you need some help with your french version, send me a pm.
