Description
Sky-High Luxury at The Halcyon | 305 East 51st Street, 30C Soaring 30 floors above Midtown East, Residence 30C at The Halcyon is a rare offering of scale, light, and city drama. This stunning 3-bedroom, 3-bathroom condominium spans approximately 2,500 square feet with 10'2" ceilings and a wraparound wall of floor-to-ceiling windows that frame breathtaking, unobstructed views of the Manhattan skyline — from the glittering East River to the iconic towers of Midtown. The heart of the home is an extraordinary great room measuring 16' x 39'6" — an expansive, sun-drenched canvas perfectly suited for grand entertaining or effortless everyday living. Wide-plank hardwood floors, soaring ceilings, and sweeping cityscape panoramas create an atmosphere that is at once dramatic and serene. The open-concept chef's kitchen features marble countertops, premium appliances, an oversized island, and a breakfast bar, opening seamlessly to the living and dining spaces. A dedicated laundry room with washer/dryer adds to the everyday convenience. The generous primary suite measures 13'6" x 22'8" and is appointed with multiple walk-in closets and a spa-caliber en-suite bath. Two additional well-proportioned bedrooms — each with ample closet space — offer flexibility for family, guests, or a private home office. A gracious 21' foyer completes this thoughtfully designed residence. Located in The Halcyon, one of Midtown East's most sought-after full-service condominiums, residents enjoy white-glove doorman service, a state-of-the-art fitness center, garage parking, bike storage, and lush garden spaces. Moments from the finest dining, culture, and transportation that New York City has to offer. This is Manhattan living at its most elevated — literally and figuratively. The advertised real estate taxes reflect the net amount after the co-op/condo tax abatement, which provides an estimated annual savings of $9,487.44 for eligible primary residents. Please note, some photos have been virtually staged.

Broker Commission Disclosure: Broker commissions are not set by law and are fully negotiable.
How working with a buyer's agent works: I work for you, not the seller. Before I show you anything, New York brokerage rules ask us to put that in writing: an agreement and a disclosure that say I work for you and negotiate on your behalf. The agreement is non-exclusive: you can work with other agents, it runs for a short fixed term we agree on, and you can end it with a note. You may attend open houses independently without an agreement. Read how it works
