Hotel Uspallata
In spite of the cavernous hallways, minimal decor, barren walls, and dim lighting (legacies of the Perón era, when the government built hotels for its employees), this grand old mountain hotel offers comfortable refuge en route to Aconcagua, Chile, or Barreal in the opposite direction. The surrounding scenery, grounds, and gardens invite long walks; the dining room is huge; and the bedrooms have closets large enough to accommodate a month's worth of clothes.
