Fodor's "It first opened its doors in 1931 but now offers contemporary amenities including a well-equipped fitness center and a spa with saunas and steam rooms"
Gayot "Guests can enjoy access to a 24-hour complimentary fitness center"
Zagat "Towering high above Central Park South, this 1931 Midtown icon (now a JW Marriott property) exudes art deco style with black-and-white marble floors and crystal chandeliers in the opulent lobby; the high-tech rooms and suites offer plenty of modern touches, such as leather-framed mirrors, wall-to-wall wooden cabinetry and free WiFi (some offer Park views and many suites have pull-out sofas with separate sitting areas), and other perks include a farm-to-table eatery and on-site fitness center"
Jetsetter "Elsewhere there’s a well-equipped 24-hour fitness center and a four-room spa; the sodashi scalp treatment or contouring marine wrap are both must-try treatments"
Star Service "A redesigned fitness center on the third floor features new workout equipment"
