Just 20 minutes driving distance far from Grenoble this beautiful place in the mid of the Alps moutains is childproof. Also it can host up to 10 p. for a relaxing and sporty weekend, hiking, climbing, paragliding, skiing, biking, snowboarding, etc.
Behave like if you were at yours. If something goes wrong, or broken, or whatever, just mention it and not conceal it. Inside of the house is not a smoking area. You have a a balcony and a big garden where it is possible to.
