    What's special

    Wood burning fireplacesVestibule with double doorsLarge dressing areaHand-carved millworkWhite marble clad galleryAbundance of closetsElegant wood paneled library
    Perfectly situated on one of the city’s most prized blocks, this stunning limestone mansion is distinguished by its elegant yet restrained façade and fortuitous placement just off Fifth Avenue. The house is also most fortunate to be flanked by and across from several houses of equivalent architectural merit, on an especially coveted block. Sun-filled, open and airy, this 22.5-foot wide residence is comprised of a total of five stories plus an immaculately finished basement. The interiors are simply beautiful, and perfectly reflect the very good taste exhibited by the exterior of the house. Moreover, the classic but updated floor plan hits just the right note for today’s lifestyle, while the serene and effortlessly chic rooms are an absolute delight. Entry is into a vestibule with double doors that open into a white marble clad Gallery that imbues the house with a European sensibility. Beyond there is a grand scale Dining Room that very easily accommodates thirty guests. The adjacent eat-in Kitchen and Pantry are absolutely pristine, and newly-renovated with a panoply of state-of-the-art appliances and fittings. Delightfully, the Kitchen benefits from serene outlooks onto the pretty garden. A wide and graciously ascending staircase leads to the exceptional Parlor Floor which is distinguished by a nice big and broad landing, nearly 11-foot tall ceilings, and hand-carved millwork. The tremendous Living Room and elegant wood paneled Library both feature charming tree-line outlooks and wood burning fireplaces. In terms of the private quarters, the very big Third Floor Master Bedroom Suite includes a fireplace, a luxurious and classic white marble bathroom, a large Dressing Area, an abundance of closets, and a lovely Study. The Fourth Floor is comprised of three spacious and sunny bedrooms with ensuite marble baths and very ample closets. And the Fifth Floor, with two bedrooms and baths, is much the same but also includes an utterly charming and most picturesque south facing terrace as well as a pretty planting terrace to the north. This sublime house is a delight in every possible way. Effortlessly, it incorporates the amenities and custom touches now expected for today’s lifestyle with prewar architectural merit and detail treasured by any discerning townhouse buyer.
