Description

Step down into this glorious sunny South facing Living Room with long French Windows and Juliette Balconies. Off to the left is a beautiful corner wood paneled library facing East and South with a wood burning fireplace and imported parquet Versailles floors from a castle in France. Off to the right is a 14.3 x 18.9 Dining Room with a gorgeous mantle and parquet floors. These three major rooms open to each other to create a large elegant entertaining space or wonderful everyday living. The romantic master suite facing Park Ave also with long French Windows has a fireplace and built in refrigerator. A marble bathroom with double sinks and a deep soaking tub and four huge walk in closets complete the master wing. The large eat-in Kitchen is the size of one you would find in a 10 room apartment. Off the Kitchen is a Staff Room/Office and private bath that can be reconfigured to open off the Dining Hall to create another bedroom and bath. 840 Park Ave is a magnificent Limestone pre-war coop built in 1912 steps from the Carlyle Hotel and the Mark and 2 blocks from Central Park. A little TLC and this is a Trophy Residence in a Gorgeous Building on Park Ave.

The Upper East Side remains the gold standard for classic New York elegance. Known for 'Museum Mile' and its quiet, 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.
