Hôtel de Crillon
Louis XV ordered the building. Ange-Jacques Gabriel gave it the long colonnaded front that still faces Place de la Concorde, and it stayed a private palace for well over a century before opening as a hotel in 1909.
A four-year restoration kept the doors shut until 2017. Rosewood now runs it, and the work brought in several decorators rather than a single house look, so salons and suites shift in mood from one floor to the next. Two apartments on the upper level were designed by Karl Lagerfeld.
What you come for is the fabric of the place. Carved panelling, marble stairs, tall windows with the obelisk framed in them.
