Apt K4 at 80 Winthrop Street is a meticulously designed one bedroom home in prime Prospect Lefferts Gardens with a rarely-seen level of customization and refinement.  The charming entryway sets the tone for this contemporary oasis. Facing South, the living room is spacious, bright, and able to accommodate a large dining set. An extra large coat closet with floor-to-ceiling storage and automatic light is discreetly hidden behind a jib door.  The Kitchen is fully renovated with custom walnut cabinetry, Carrara marble countertop and backsplash. The appliance suite includes Miele dishwasher/hood, Bertazzoni cooktop/oven, and Blomberg refrigerator.  The bedroom is a perfect blend of form and function, with a large custom-built walk-in closet and a home office/vanity, separated by a pocket door with Hawa soft-close hardware, offering ample shelving and storage.  All electric wiring, fixtures, and outlets have been upgraded and rooms are fitted with Lutron dimmers. The spa-like bathroom with brand new plumbing features a walk-in shower with marble floor tile, Duravit toilet, Hansgrohe faucet and thermostatic shower control, Speakman shower head, and two Kohler medicine cabinets. Subtle details add to the overall comfort of the home. Original, refinished wood floors, skim-coated walls and ceilings, brand new wood doors with Baldwin door hinges and Rejuvenation mortise lock door knobs, all enhance the overall aesthetics and separation of live/work.  80 Winthrop is a well-maintained coop just a few blocks from Prospect Park. The building has two laundry rooms, a bike room, live-in super, two porters, and a communal landscaped courtyard. Transportation options are abundant with the Q, B, 2, and 5 all within a short distance. Neighborhood favorites Loud Baby and Cinnamon Girl are perfect for weekend coffee jaunts and visits to the Brooklyn Botanic Garden, not to mention local eateries Risbo, Bonafini, Camillo, and Edie Jo at your doorstep. Open house and showings by appointment. Pets not allowed.
