Mylène and Elizabeth love the outdoors, hence their five-year fight to reincarnate a fallen ruin as a luxury mountain retreat. Join them for gourmet dinner under soaring, raftered ceilings in the grand living space which hovers above Tignes dam. Or soak in the terrace hot tub under the stars; there’s a sauna too. Urban rusticity, mountain chic: the place reeks Italian style yet is impossibly hidden in this tiny hamlet. For daytime adventure: the slopes at Val d’Isère, or Tignes, or the Vanoise park. Just ask Elizabeth, off-piste skier extraordinaire.
