Description
Welcome to Unit 4B, where upon entering, you are immediately greeted with a warm and inviting gallery space, outfitted with a large closet and plenty of space to unpack and unwind. To your right is the appropriately named great room, an open-plan living and dining space with beautiful white oak floors and a wall of park-facing windows that provide an ideal backdrop for lounging, dining, or cooking-perfect for either entertaining or a quiet night at home. A large Caesarstone countertop and dining bar connects the kitchen to the larger space, providing social flow and extra seating if need be, while the kitchen itself, of course, is outfitted with a high-end Miele appliance package across the board. There is also an in-unit Miele washer/dryer, adding convenience to classic comfort. Unique to this unit is the solarium, an indoor sun-room with another western exposure-directly facing the lush greenery of Central Park, and in the fall or winter, overlooking the pond. It's a rare space to slow down with your morning coffee, reading or relaxing while savoring the tranquil park views whatever the season. 923 Fifth Avenue is a historic 21-story building with an Art Deco flair and a limestone base that was built in 1950 and converted to a condo in 1983, right in the heart of the landmarked Upper East Side Historic District. With a flexible and resident-friendly policy, this condominium allows pets, pied-a-terres, subletting, co-purchasing, and financing, only adding to its rare-find status on Fifth Avenue. The building is also full-service and amenity-rich, featuring a 24-hour doorman, live-in superintendent, fitness room, central laundry room, bike room, building storage, and on-site parking. Simply put: This residence will not be like any other home you find in your search. Dare to make it yours.
