Gilded-age floor-through residence with a rare combination of generous light, private garden, contemporary finishes, and townhouse charm. Located on a quintessential Central Park block, this home encompasses the original parlor floor and 21’ wide garden of an 1893 Renaissance Revival brownstone. Inviting, loft-like Living Room features south-facing picture window, wood-burning insert fireplace, and home theater with exposed brick surround. The home is perfect for entertaining, with chef's Kitchen tastefully framed by architectural glass, across from a spacious Dining with pendant chandelier. The full-width Primary Bedroom Suite includes a glass + marble bath with a shower and soaking tub, as well as an enormous WIC that you can actually walk into. South + east-facing Second Bedroom/Office with built-in bookshelves opens to the huge private garden. The approx. 550 sq. ft. of Private Outdoor is actually three spaces: an elevated balcony off of the second bedroom, a functional area below with water point and outdoor electric, and a huge 21’ x 17’ garden with irrigation system and custom lighting. This parlor-floor stunner was completely renovated by the current owner from a 3 bedroom, 2 full bath into a the current grand 2 bedroom plan with private W/D installed in the second bathroom. 10'8" ceilings, recessed lighting, hardwood floors and central A/C throughout. No. 20 is a superbly self-managed boutique 4-unit coop. West 90th is one of the finest blocks on the Upper West Side just a few doors from Central Park, and close to myriad shopping, restaurant, school, and transportation options. There is building laundry and a private storage area for this apartment in the basement. Cats welcome, with dogs permitted on approval.
