Intensive French Courses In the UK

Hello all

I am really enjoying the steady progress I am making with my French studies (thanks for all your help!) but I would love to be able to take a big step forwards by attending an intensive French course. Has anyone here attended one of these and could you recommend any to me?

In the ideal world, of course, I'd like to do a longer course...and in France rather than UK. But due to other commitments, one week in London suits me pretty well at the moment. Alliance Française de Londres also offer an intensive course in London, but this is 30 hours over 2 weeks.

Any suggestions/recommendations would be very welcome.

Merci d'avance

Jon
