Distinguished by the scarlet flowers cascading over its elegant facade, this glamorous landmark hotel sits on one of the most expensive avenues in Paris. As part of a top-to-bottom face-lift in 2014, the hotel annexed two neighboring town houses and added six new guest rooms, eight suites, a ballroom, and two event spaces. The suites' interior design, led by Marie-José Pommereau, expertly places contemporary pieces in a luxe traditional setting, culminating in the two quintessentially Parisian Eiffel suites, where the looming tower is framed by floor-to-ceiling windows. Sumptuous rooms enchant with designer furnishings and luxurious conveniences like remote-control air-conditioning, compact sound systems, and even a pillow menu. Alain Ducasse's signature restaurant—a contender for best restaurant in Paris—was given a glittering new look that reflects the hotel's haute-couture grandeur, with hautecuisine to match. But the laid-back landmark Relais Plaza brasserie is an excellent, and reasonable, alternative. Relax intrendy Le Bar, redesigned by the Paris-based designers Jouin-Manku to draw a hip, young crowd—it's an ideal haven for perfectly blended cocktails and celebrityspotting.
