Have you tried any of the guiding operations in the area? Often they sound expensive up front but if you add in all the food and guiding (you will need a guide over there!) its actually a bargain.
but if not, my parents have a nice place just down the road from bourg in Villette, Aime – its a short drive to the funnicular (and you can ride back to the chalet at the end of the day from up on the hill).
Garage, 4 bedrooms, nicely done out, etc. They use it just for themselves mostly, but rent it out to friends-of-friends as well.
drop my mum an email for more details if you are interested – hijamieson@yahoo.co.uk – its heather.
