The centerpiece of the home is a 43-foot long great room that sits just off the foyer and is completely surrounded by wall-to-wall floor-to-ceiling windows. It leads out onto a stunning 671 sq. ft. solarium and terrace. The residence has an upper level where four of the bedrooms are located. Entering the master bedroom is like coming into a total retreat from city life. It has every amenity you could hope for — and then some — including floating wall panel, a massive walk-in closet with custom cabinetry, and an extra-large master bathroom, his-and-her Duravit toilets in private stalls, a walk-in rain shower, and a separate free-standing bathtub. Each of the other three bedrooms each also has its own private bathroom. Have a look around this magnificent New York apartment.
