A Gluten Free Hotel in the Alps.
I have had the same problem, with major ski tour operators saying 'wecan only offer catered challets, I'm sure if you chat to your host maid she won't cook with bread or flour'.
I've just been to a small hotel in the German alps, Garmisch-Partenkirchen.
It's run by Darren & Michelle. Darren is a Coeliac himself...
