This grand mansion-like residence brings the adaptability of a townhouse to the comfort and privacy of the Upper West Side's finest full-service condominium. 6-18 fills the entire southwest wing of the 1904 belle-epoque landmark building, on a select floor with raised 10.5 foot ceilings. The entrance gallery leads to a 3-exposure, sun-filled 50-foot wide living/entertaining area. Chef's kitchen includes 2 sinks, wide refrigerator, wine cooler, and custom marble island, open to the large family room and bay-window banquette. The living room feels more like a ballroom, with window seats, decorative fireplace, and french door window sashes. Discreet frosted glass pocket doors can divide the space for formal entertaining. The 2nd and 3rd bedroom suite include generous closets and a shared full bathroom. Across the gallery is the discreet powder room. The Master Bedroom creates a large, welcoming heart to the home. The windowed dressing room features two walk-in closets, and leads to the spa-quality 5-piece master bathroom. The large, fourth bedroom/sitting room opens from the master suite, or can be accessed separately via the main hallway. The final bed and bathroom creates an ideal guest suite, staff suite, semi-detached family accommodation, or private home office. A one-of-a-kind residence with 3,250 sq. ft., over-sized windows with Juliet balconies, cushioned window seats, 4-zone central A/C, Lutron lighting, "smart home"-ready structured wiring, in-wall speakers, and herringbone hardwood floors. The Ansonia, since 1904, has been the shining example of fine Beaux-Arts and baroque architecture in Manhattan. There is no more convenient location for comfortable living in Manhattan. Central Park is nearby, as is all transportation, Fairway Market, Citarella and Trader Joe's around the corner. Lincoln Center is just a few blocks south. Full-service building with doormen, concierge, garage, stunning roof deck, laundry, bike racks, and storage. Annual: $32,000 Per Month
