Description

Welcome to your dream home at The Florence. This stunning, turn-key combination residence is a beautifully designed three-bedroom, two-and-a-half-bath duplex that seamlessly blends luxury, charm, and scale in the heart of the Upper West Side. Offering the warmth and privacy of a townhouse with the convenience of full-service cooperative living, this exceptional home is nestled within The Florence, one of West End Avenue's most distinguished prewar cooperatives.

Spanning two thoughtfully designed levels with separate entrances on each floor, this expansive residence offers gracious proportions, timeless architectural detail, and an ideal layout for both everyday living and entertaining.

The main level is anchored by an oversized living room featuring coffered ceilings, herringbone hardwood floors, and beautiful natural light throughout the day. French doors lead into a formal dining room perfectly suited for elegant dinners, holidays, and entertaining. The windowed kitchen is both functional and inviting, complete with abundant cabinetry, stone countertops, and a charming breakfast nook ideal for casual dining. Also located on this floor are two split bedrooms, offering flexibility for family living, guests, or a dedicated home office, as well as a full bathroom conveniently positioned off the hallway.

The upper level is devoted entirely to an extraordinary primary suite, creating a quiet and private retreat from the rest of the home. The oversized bedroom is complemented by a spacious en-suite bath and an expansive walk-in closet that functions as a true dressing room. Discreetly integrated within the massive oversized closet area is an in-unit washer and dryer, delivering a rare level of convenience for a prewar residence. Central AC on the top floor.

Built in 1924 and converted to cooperative ownership in 1983, The Florence is a 16-story, full-service cooperative comprised of 95 residences. Amenities include a full-time doorman, laundry room, nursery/playroom, and common storage. Financing is permitted up to 75%, and the building offers approximately 37% tax deductibility.
Perfectly positioned between West 86th and West 87th Streets, moments from Riverside Park, transportation, and some of the Upper West Side's finest dining and shopping, this elegant duplex offers a rare opportunity to own a substantial and beautifully laid-out home on iconic West End Avenue.
