Originally opened in 1906 by John Jacob Astor, the 330-room Knickerbocker exudes a restrained, monochromatic elegance. Rooms are dashingly chic, hushed and modern, decked out with adjustable 55in flat-screen TV, bedside tablet and USB charging ports, as well as Carrara-marble bathrooms. Triple-glazed windows keep it wonderfully serene inside, but the Times Square location means perpetual chaos right outside the front door.
Hotel facilities include a sophisticated lounge (with live jazz Tuesdays to Thursdays 6pm to 9pm), cocktail bar and Modern American bites, as well as a fabulous rooftop bar with on-site humidor and occasional DJs. This bar is about 130ft from the Times Square New Year's Eve ball (hoisted late November), and hosts an exclusive countdown party on December 31 each year.
