Large, Sunlit, South-facing Junior 4 in prime Upper East Side location. At approximately 850 square feet, this move-in-ready home features a generous layout, oversized windows, beautiful hardwood floors throughout, abundant storage, and through-the-wall A/C. This apartment presents a rare opportunity to own a convertible 2-bedroom home at an incredibly attractive price. The heart of the home is the impressive 23-foot-long living room, where abundant southern light streams from the oversized windows and fills the space with all-day natural light. Just off the living room, the dining alcove offers maximum flexibility. Keep it open for meals and entertaining, use it as a work-from-home office or enclose it to create a comfortable second bedroom. The renovated pass-through kitchen is outfitted with stainless steel appliances, custom cabinetry, and valuable storage and prep space. For those seeking a more open-concept layout, the kitchen can also be opened to the living room, creating an even more expansive, loft-like feel. The oversized primary bedroom comfortably accommodates a king-size bed with plenty of space for supporting furniture and is fitted with a large wall-to-wall closet. In total, there are four oversized, built-out closets in the apartment, providing exceptional storage and organizational space throughout. The layout is completed by a tiled bathroom, featuring a soaking bathtub and a vanity. Adding a W/D is now permitted with board approval.
