Agent's Note
From Curtis Bain. Details about the apartment are drawn from the listing information provided through RLS by Corcoran Group.
The washer and dryer sit inside the apartment, so laundry never means leaving the unit. The kitchen has been fully renovated with custom cabinetry and premium finishes, and the listing describes the whole home as turnkey, with every room updated.
The layout gives you a generous living room, a separate dining area and a spacious library. That's a useful mix, since the entertaining rooms and a quieter room don't compete with each other. I like that the library is a real room with a door you can close, and a fireplace adds warmth to the main living space. There's also a staff room.
The building is a prewar cooperative designed by Rouse & Goldstone, with 12 stories and about 50 residences. A 24-hour doorman and a live-in superintendent are on site, and the lobby keeps its classic Park Avenue character. An elevator serves the building. Storage is assigned, bicycle storage is available, and there's a fitness room, a basketball court and a courtyard. Pets are allowed.
Central Park is about 5 minutes away on foot, and the Metropolitan Museum of Art is about 7 minutes. For everyday errands, Gristedes is about 5 minutes away, and the 86 Street station on the 4, 5 and 6 lines is about 7 minutes on foot.
Pied-a-terre ownership is permitted with board approval. It's worth confirming with your attorney how that applies to your plans before you move forward.
