This gorgeously renovated three-and-half-room duplex is located in a handsome 1889 townhouse on a charming tree-lined Carnegie Hill street (between Park and Madison Avenues), a block and a half from Central Park. The classic architectural details of the distinguished space are highlighted by ten-foot ceilings and a wall of windows in the upstairs living area, a decorative fireplace, recessed lighting, a marble-topped dining island, high-end appliances, custom cabinetry, and built-in bookshelves. A washer/dryer is located in a separate laundry room/pantry.An oversized primary bedroom on the lower level has been divided to create a separate guest room/nursery and features exposed beams, pocket doors, custom closets, and generous storage space. There is also a built-in office space downstairs. Both upstairs and downstairs floors have luxurious, spa-quality bathrooms. The co-op allows cats but no dogs as pets. Subletting is on a case-by-case basis with common limits. Sorry, no co-purchases. Gifting is OK, but not preferred. Pied-a-terres are also not preferred. This self-managed building was presented the 2017 Neighborhood Enrichment Award by the Carnegie Hill Neighbors for the restoration of the front facade. There is a 2% flip tax paid by the purchaser.
