New York's most exceptional suites are penthouses in all but name: wraparound terraces forty or more floors up, Central Park spread out below, private gyms, chef's kitchens and grand pianos in the living room. Butlers and chauffeured cars come with the territory, and well-connected concierges can secure courtside seats, sold-out tables or a private after-hours gallery viewing. Height and silence are the true currency, and the towers around Central Park and the Upper East Side's discreet townhouse suites deliver both.
