Description

Welcome to Residence 6A at 350 South 4th Street, a fully gut-renovated one-bedroom HDFC with incredibly low monthly maintenance of just $350. Set on the sixth floor with multiple exposures, the home is flooded with light . Every inch of the apartment has been remodeled with quality and care form the new light fixtures down to the wide plank oak floors. The windowed kitchen is the centerpiece. Featuring a marble slab backsplash, white quartz counters, and custom shaker cabinetry with brushed-nickel hardware. Stainless steel appliances and gas burning stove. A breakfast bar sits at the window and a full wall of built-in shelving provides pantry and display space. The sunny living room has a full wall of custom millwork. That wall includes floor-to-ceiling cabinetry, a deep bank of drawers, and an open media niche. Room for a lovely sectional sofa and plenty of space to gather. The bedroom comfortably fits a queen-size bed. It has swing-arm sconces on either side, a ceiling fan, and open rooftop views. The custom built closets allow for maximum storage space. The bathroom feels like a boutique hotel. It has a frameless glass walk-in shower with large-format marble tile and a built-in marble bench. A sculptural marble console sink sits on an iron base with a wall-mounted polished-nickel faucet, flanked by twin framed medicine cabinets and a vintage-inspired sconce. Residence 6A is a sixth-floor walk-up - just five flights up, and the reward at the top is light . It is moments from the best of Williamsburg's dining, shopping, and waterfront, with easy access to the J/M/Z and L trains. This is an HDFC co-op. Income restrictions: AMI - 120% which equals $130K. Flexible sublet policy. Pet friendly.
