This elegant pre-war condo pairs classic architecture with a refined, modern sensibility. Thoughtfully reimagined, the residence offers beautiful light, generous proportions, and a well-considered layout designed for everyday ease.

A gracious entry foyer features custom designer wallpaper, a hidden, built-in shoe closet, and a separate coat closet for effortless organization.

The large sunken living room is framed by oversized windows with treetop and architectural views. Custom millwork adds both function and visual interest, while the space flows seamlessly into an open dining gallery - perfect for intimate dinners or larger gatherings.

The windowed kitchen, which can be closed off with an elegant oversized pocket door, is outfitted with stone countertops, custom cabinetry, and premium appliances, including a Sub-Zero refrigerator and wine cooler, as well as a Thermador range and dishwasher. Both the refrigerator and dishwasher are custom-paneled to blend seamlessly with the cabinetry. A sun-filled breakfast nook completes the space, adding warmth and charm.

The private bedroom wing offers a serene retreat. The primary suite boasts treetop views, a step-in closet, and a windowed en-suite bath with custom tilework, Waterworks fixtures, and a rain shower. The second bedroom features a walk-in closet, with easy access to a windowed marble bath including an oversized soaking tub and Waterworks finishes. A separate, fully outfitted California Closet room off the hallway provides exceptional, boutique-style storage.

Additional apartment features include beamed ceilings, hardwood floors, central air conditioning, a brand-new Bosch washer and dryer, Fios fiber optic service, and three exposures providing distinct perspectives of the neighborhood.
