923 Fifth Avenue is one of the few white-glove condominiums on Fifth Avenue, in the heart of the prestigious Upper East Side. There is no Board Approval required for purchase, and both financing and subletting are allowed.
Just as a vivid fancy-colored diamond is intense, Apartment 15B is exceedingly rare. Offered for the first time in 24 years, 15B is in the front of the building, facing Central Park, with a private, setback outdoor patio for the most incredible views. Nestled between 923 Fifth Avenue's two major A and C-lines, the B-line feels ike a five-star hotel suite, measuring a spacious 1200 square feet, with a huge oversized primary bedroom. At 923 Fifth, the three Park-facing lines, the A, B, and C lines, are the most valuable and rarely for sale. Most Fifth Avenue architects place the grandest apartments up front, and, all things considered, Apartment 15B would be impossible to duplicate today.
For the pied a terre buyer or ex-New Yorker, 15B is a highly desirable alternative to a hotel or club. For co-op down-sizers, it's the perfect white-glove, high-service UES location, and for investors, an enduring and strategic luxury asset.
In preparing the property for sale, the owners have restored the apartment to an immaculate "white box" state, with fresh paint and refinished floors. Many original details, such as custom fixtures in both bathrooms, and period built-ins in the second bedroom, were left intact. There are no summer work rules for renovators.
The apartment features a large, gracious entry foyer, king-sized primary suite, a secondary bedroom, two full baths, a windowed galley kitchen, original herringbone hardwood floors, thru-wall A/C, and generous, deep storage space throughout. Pets and in-unit washer/dryers are allowed. Located on the corner of East 73rd St and Fifth Avenue, this Lenox Hill location is arguably second to none, with delightful destinations in every direction.
In-person showings by appointment are welcomed 11-4pm Monday-Friday with 24-hr notice. 923 Fifth does not allow weekends showings. The views from 15B are transformational -- seeing is believing!
