Description

High above the Financial District on the 18th floor of one of Downtown Manhattan’s most sought-after full-service condominium residences, Residence 18C offers an exceptional blend of space, luxury, and convenience. This oversized and highly desirable C-line home spans approximately 832 square feet and features nearly 10-foot ceilings, abundant natural light, and peaceful southern exposures showcasing skyline and water views. Designed with both elegance and functionality in mind, the residence has been thoughtfully upgraded throughout. Rich hardwood floors flow seamlessly from room to room, while the contemporary chef’s kitchen is appointed with sleek cabinetry, a fully integrated Liebherr refrigerator, and an upgraded Miele dishwasher. Additional comforts include an in-unit Miele washer and dryer, along with multi-zone heating and cooling for personalized climate control. The spacious primary bedroom serves as a private retreat, complete with a custom California Closets walk-in closet and an additional closet providing exceptional storage. The spa-inspired bathroom offers a luxurious experience with an oversized soaking tub, separate rain shower, illuminated medicine cabinets, and a generously sized vanity. A dedicated home office area is enhanced by custom built-in shelving and desk space, motorized roller shades, and elegant sheer window treatments. Residents of 15 William enjoy one of Downtown Manhattan’s most impressive amenity collections, including a 50-foot heated saltwater lap pool, outdoor hot tub, sauna and steam rooms, state-of-the-art fitness center with complimentary fitness classes, yoga studio, squash court, outdoor half-court basketball court, children’s playroom, valet parking, 24-hour doorman, concierge service, and a live-in resident manager. The building is further distinguished by its spectacular penthouse sky lounge and landscaped rooftop terrace. Perfectly positioned in the heart of the Financial District, the residence is moments from Whole Foods, the Seaport, Tribeca, and Battery Park, with easy access to some of Downtown’s finest restaurants, shopping, and waterfront destinations. Commuting is effortless with nearby access to the 2, 3, 4, 5, 6, J, and R subway lines, PATH trains, Citi Bike stations, and NY Waterway ferry service. Optional storage locker available. No Pets
