Welcome home to this extremely special 3 bedroom 2.5-bath duplex in the coveted Ansonia Court. Historic charm mixed with modern amenities invite you into an urban-chic haven, a calm refuge from the city outside. This home feels more like a townhouse than a co-op with soaring rustic beamed ceilings, exposed industrial brick, and oversized arched windows that flood the home with natural light.

Step into a sprawling living area, an oasis with hardwood floors and towering ceilings. Walk right by the carefully hidden in-unit washer /dryer into an expansive and sun-filled open kitchen/dining room with oversized South-facing windows. Off of the kitchen on the first floor is a powder room with serene spa sensibilities. An endless walk-in closet is hidden under the wooden staircase for additional storage. Up the stairway awaits your dream primary bedroom, with extra large in-suite bathroom, tiled shower and hand-built cabinetry. Two more generous-sized bedrooms share another full bathroom with a vintage double wall-mount sink. Each room has been thoughtfully redesigned and updated for modern living and comfort. This unit comes with roof rights.

Tucked away through the courtyard is the private entrance to building F. It is surrounded by a lush lawn, a fountain, benches and ideal landscaping that all provide a peaceful retreat and common area for all residents to use.
