Grand, gracious, and filled with light, this expansive residence—featuring 4 bedrooms, a library/home office, and an elegant formal dining room—spans nearly 3,000 square feet in a classic 1914 prewar cooperative. Thoughtfully renovated, the home features soaring 10-foot ceilings, oversized windows with south, east, and north exposures, original architectural details, beautiful hardwood floors, and an in-unit washer and dryer. With only two apartments per floor, the home offers exceptional privacy and quiet. A semi-private elevator landing leads into a formal gallery, which opens to a nearly 20-foot-wide, sun-filled living room overlooking treetops on West 86th Street. Adjacent is an expansive formal dining room—ideal for large-scale entertaining or easily repurposed as a den or secondary living space. The layout is intelligently designed with two separate bedroom wings for optimal privacy. The southern wing includes a spacious corner primary suite with sunlit south exposure, ample closet space, and a serene en suite bath with double sinks. A second bedroom, currently used as a library or home office, can be easily converted into a fifth bedroom. The northern wing features three generous bedrooms—one currently configured as a secondary living room—along with two full baths and abundant closet space. The windowed, eat-in kitchen is both stylish and functional, complete with a handsome bar area and wine refrigerator, large pantry, charming built-in banquette for casual dining, and a custom desk nook. Perfectly located in the heart of the Upper West Side—just moments from both Central Park and Riverside Park—151 West 86th Street is a distinguished full-service cooperative offering a part-time doorman (7 AM–12:45 AM daily), live-in superintendent, private storage, bike room, central laundry, and a beautifully landscaped roof garden. Pets are welcome, and 65% financing is permitted.
