Set within a meticulously restored 1901 Beaux-Arts landmark between Central and Riverside Parks, this four-bedroom, three-and-a-half-bathroom duplex at The Marbury Condominium offers something genuinely rare on the Upper West Side: one thousand two hundred fifty-seven square feet of private outdoor space across four separate exposures, paired with two thousand five hundred thirty-two square feet of interior across two floors. Ten-foot-plus ceilings, southern light throughout, and a deeded storage unit round out the offering. A keyed elevator opens directly into the apartment, arriving at a gracious foyer that gives way to an expansive living and dining room. The chef's kitchen is outfitted with top-tier appliances and a vented hood, and a wall of sliding doors leads to a private balcony off the main living space. Three bedrooms sit on this level. The south-facing primary suite has its own balcony, a custom walk-in closet, and a marble bathroom with heated floors. Two additional bedrooms share a full bathroom, and a stylish powder room completes the floor. A sculptural spiral staircase rises to the upper level, an entertaining floor anchored by a fourth bedroom, full bathroom, and a gallery with built-in wet bar, all set between two terraces of approximately five hundred ninety and five hundred eighty square feet. The result is an indoor-outdoor configuration few Manhattan apartments can match, with open sky on multiple exposures and sightlines toward both parks. The Marbury's amenities are calibrated to the architecture: a twenty-four-hour doorman, a wood-paneled private dining salon, a billiards room, and a residents' lounge with wine storage and kitchenette opening onto a landscaped courtyard. A fitness center with cardio equipment and an interactive training mirror completes the package. Positioned between two of the city's great parks and steps from the one train, two trains, and three trains; the apartment sits at one of the most desirable crossroads on the Upper West Side. Some images have been virtually staged. Twenty-four-hour notice required for all appointment requests; please contact us to schedule a viewing.
