Considered a mansion by some, a château by others, Cour des Vosges is experienced as an exceptional residence welcoming epicures, hedonists, history buffs, and lovers of Paris. The butler hands over the key to the 12 rooms and suites, each of which feels like a pied-à-terre. Each landing recalls the architectural features of 17th-century buildings. Each hallway seems to lead, as in the past, toward stately apartments.
