Description
Bathed in light and beautifully proportioned, Residence 18D at 15 William Street is a spacious 698 sq ft studio framed by oversized windows with sweeping open views of the river and skyline.
The layout is designed for both ease and versatility, with thoughtfully defined areas for living, dining, and sleeping. Custom window treatments and Burmese teak floors bring warmth and texture, while a cleverly integrated Murphy office provides a discreet, built-in workspace that tucks away effortlessly.
The kitchen pairs style and function with Miele and Liebherr appliances, white lacquer cabinetry, and Caesarstone counters. The spa-style bath features a deep soaking tub, a rain shower, and refined modern fixtures. Louvered doors allow sunlight to filter through to the dressing area, home to a generous walk-in closet, creating a bright yet private space to get ready each day.
An in-unit washer/dryer completes the residence.
At 15 William, residents enjoy a comprehensive collection of hotel-style amenities, including a 24-hour doorman, state-of-the-art fitness center and yoga studio, indoor lap pool and outdoor hot tub, basketball and squash courts, screening room, children's playroom, dog run, and rooftop lounge with a sundeck, kitchen and panoramic views.
Set in the heart of the Financial District, moments from the Seaport, Stone Street, and multiple subway lines, 15 William offers a seamless downtown lifestyle where comfort, design, and convenience meet.
