Step inside Apartment A at 24 West 90th Street and you'll immediately understand why this historic stretch of the Upper West Side is so beloved. Just off Central Park West, on a quiet tree-lined block, this 1,960 square foot duplex residence offers the rare combination of townhouse charm, private outdoor space, extremely low maintenance and modern convenience-all in one of Manhattan's most sought-after neighborhoods.   The open-concept main level unfolds with an airy living and dining space where vaulted beamed ceilings, hardwood floors, and oversized windows bathe the home in natural light. A thoughtfully renovated kitchen anchors the space with stainless steel appliances, granite countertops, and custom cabinetry, perfect for both weeknight dinners and weekend entertaining. The main level also features a spacious primary bedroom with an ensuite bathroom with double sinks, a second bedroom with two large, sunny windows overlooking the garden, and a large family room with a glass wall and door leading outside. And then there's the showstopper: a private garden patio with southern exposure and Ipe decking, your own oasis in the heart of the city. Morning coffee, dinner parties under the stars, or a quiet escape with a book-this is outdoor living, New York style.  With over 560 square feet of space, you can create your own retreat, the space is wired for electricity and water. Downstairs, the residence continues its flexible plan with an enormous living room with vaulted 17-foot ceiling, wood burning fireplace and large built-In bookcase.   A home office and beautifully tiled full bathroom, give you room to entertain and to spread out and create the lifestyle you want. There are many closets throughout the home and a large in-unit private storage area. Behind a door a new oversized washer and dryer services the building. A washer and dryer in unit would be permitted by the board.   Set within an intimate prewar co-op, 24 West 90th Street offers a boutique living experience with Central Park as your backyard. This self-managed coop has no underlying mortgage, keeping your monthly cost incredibly low. Pets are permitted (one per unit and small breeds only) and parents buying for/with a child, gifting and part time residences are all considered by the coop. The coop is financially sound and is up to date on all capital improvement projects including a new HVAC, new facade, re-roofing and upgrade of gas pipelines. There are no current assessments and none upcoming. Flip tax of 1.5% paid by buyer.   Just moments from the B and C trains at 88th Street, 1 lines at 86th or 94th and Broadway and crosstown bus on 86th Street. For the outdoor enthusiasts, you are less than half a block from Central Park, The Reservoir and Central Park Tennis Courts. Grocers abound with Trader Joe's, Whole Foods and D'Agostino all within a few blocks. Don't miss some or our favorite restaurants outside your doorstep; Trattoria, Bella Luna, Barney Greengrass, Good Enough to Eat and Gennaro.   Apartment A is more than just a home-it's an opportunity to own a piece of the Upper West Side real estate market that rarely becomes available.
