18 Gramercy Park South is one of Manhattan's most coveted addresses, offering the rare privilege of direct key access to the only private park in New York City. This full-floor residence occupies the 14th floor of a landmark prewar building, combining original architectural details with a thoughtful contemporary renovation. The living and dining rooms face the park directly, framed by oversized windows that invite natural light throughout the day. The primary suite features a separate dressing room, dual marble bathrooms, and views that stretch across the treetops. A building of this caliber, at this address, rarely becomes available.
