On the south side of the apartment, there's a den/family room and large dressing room, both south facing, connected by a windowed Jack and Jill bathroom. Both of these rooms are possible bedrooms and are used as such in other D-lines in the building. The den/family room is a very large room, over 20 ft long, with a WIC.

The Upper East Side remains the gold standard for classic New York elegance. Known for 'Museum Mile' and its low-traffic, tree-lined streets, the neighborhood offers a refined lifestyle away from the midtown bustle. While famous for its historic cooperatives, the area has seen a recent surge in ultra-luxury new construction condos, particularly along the Second Avenue Subway corridor, making it a top choice for both traditionalists and modern buyers.
