Combining the old world glamour of a private mansion with the luxury of a modern apartment, this gigantic duplex apartment is set within one of Manhattan's most desirable buildings, along a quiet stretch of the East Side's elite Sutton Place neighborhood. A true duplex, this spacious home is really three apartments combined into one, spanning a full 6,000 square feet. Sweeping views stretch out in every direction, with north, south, east and west exposures throughout the apartment, including a particularly spectacular vista of the 59th Street Bridge. Eight separate bedrooms provide for a wide variety of possible uses (the current owners have arranged a breakfast room, a meditation room and an office), while the formal dining and living room offer ample space for entertaining, and the dramatic entryway is lined in imported marble. Additional spaces include a private landing, balcony, media room, and 7.5 bathrooms. This incredible home is equipped with every modern convenience, including zone controlled central heat and air conditioning, and an in-unit washer and dryer. One of the East Side's most sought after coops, The Sovereign is a full-service luxury building complete with a 24-hour doorman, concierge, and on-site garage with valet parking. The travertine marble lobby features soaring ceilings accented with hand-blown Venini chandeliers from the 1950s Italian architect Carlo Scarpa, and was recently updated by noted designer Harry Allen, whose furnishings are in the Museum of Modern Art's permanent collection. Additional on-site amenities include a fitness center, bicycle room and mail center.
