Beautiful and dramatic, the SLS Hotel at Beverly Hills is a fantasy of design, set right in the heart of Los Angeles’ most decadent neighborhoods. Decorated by the inimitable Philippe Starck in a style that blends ornate wingback chairs with floor-to-ceiling mirrors and midcentury-inspired leather sofas, the hotel feels like a movie set that happens to welcome live-in guests. Creative dining from James Beard Award–winning chef José Andrés attracts L.A. scenesters and culinary aficionados from around the globe to dine on its Spanish-inspired molecular gastronomy. The 5,000-square-foot, all-white-and-chrome spa is the kind of place dreams are made of, and it wouldn’t be surprising to hear that Mr. Starck conceived the design in a celestial dream. But the crowning glory may be up on the roof, at the Altitude Pool, a glamorous oasis lined with plush loungers, ornate cabanas, and fantastical decor, where L.A.’s rich and beautiful come to play. If this is the SLS world, it’s a good place to be.
