Actual photos! Welcome to your tranquil retreat in this spacious, south-facing condo on a quiet, tree-lined street at the edge of the Upper East Side, between Park and Lexington Avenues. Modern double-paned windows enhance the natural calm of the location. The thoughtfully designed open floor plan features a stylish, expansive 29' living room—ideal for entertaining—highlighted by recessed lighting. The unit includes two king-size bedrooms, a separate bonus room with a sliding door, a spacious windowed bathroom with a tub/shower combination and vanity cabinet, and a kitchen with two windows that let in evening night. The apartment is in excellent, move-in-ready condition, with ample kitchen storage, granite countertops, and updated stainless steel appliances, including a Maytag refrigerator, GE stove, microwave, dishwasher, and wine cooler, plus a Whirlpool washer and dryer. Updated pre-war details include high ceilings, hardwood floors, moldings, and a working marbled wood-burning fireplace with a mantel. Ceiling fans in the living room and bedrooms enhance airflow, improving the efficiency of the heating and cooling units. The apartment has its own Navien combination boiler, providing on-demand hot water and baseboard heat via a thermostat. Installed approximately three years ago, it remains under warranty. (Navien boilers, with proper maintenance, can last 20 years. The current owner recently installed a special filter believed to extend its lifespan and can recommend the trusted HVAC expert who has serviced the unit annually.) Located in a five-story, pre-war, non-elevator condominium, Unit 4A is three flights up. The building is investor-friendly and managed internally by an experienced condo board. Pets are welcome and the sublet policy is generous and uncomplicated. Enjoy quick access to cultural and entertainment venues, gourmet restaurants, and shopping. Nearby are Mount Sinai Hospital, The Museum of the City of New York, the Museum of Jewish Heritage, El Museo Del Barrio, Central Park, and the Central Park Conservatory. Convenient transit options include the 4 and 6 Lexington Avenue subway lines at 96th and 103rd St. stations.
