Uniquely Park Avenue: This exceptional residence is the epitome of timeless elegance. A seamless blend of space, light, and sophistication in the toniest heart of the Upper East Side. Visitors are wowed the moment they step into the grand foyer, which opens to an expansive living area with impressively high ceilings and oversized windows that shout modern luxury and Golden Age grandeur. It's as airy as a house and as comforting as home, with a working wood-burning fireplace, warm herringbone flooring, and plenty of custom closets, shelving and cabinetry to stash your valuables and assert your style. Lots of listings claim to have a chef's kitchen but this one truly does, featuring a 6-burner commercial Garland gas range, double oven, flat top grill, and even a dedicated pizza oven for partying. It's a multi-windowed eat-in space too, with a peninsula prep counter, two pantries and, of course, the obligatory Sub Zero. Behind the kitchen is a versatile den with full en-suite bath that originally functioned as quarters for household help. It still can. Or it can become a kids' room or a very private home office. The secluded sleeping quarters, located in the opposite wing, contain a corner Primary Suite with a walk-in closet, and a luxurious spa bathroom decked out with a steam shower, soaking tub, and bidet. A spacious second bedroom, full second bathroom, and additional super-jumbo walk-in closet complete this retreat.
