If you're a model, actor, celebrity, or just act like any of the three, you'll feel right at home at The Mercer. Housed in a landmark Romanesque revival building, this is a see-and-be-seen hotel that's all about mod luxury. All rooms have supersleek Christian Liaigre interiors that artfully mix soothing neutral colors, hardwood floors and rich materials like leather upholstery and 400-count Egyptian-cotton linens. Bathrooms are just as inviting, with oversized marble tubs big enough for two and bath products from Swedish company FACE. Too tired to unpack? No problem—the staff can take care of that. Need a private trainer? They've got it (and plenty of other personalized services) available, too. If all that weren't enough, Jean-Georges Vongerichten's supersexy American-Provençal restaurant, Mercer Kitchen, is onsite.
