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.
