Description

Fully reimagined with a meticulous, design-forward renovation, Residence 7D at 121 East 23rd Street is a beautifully appointed two-bedroom, two-bathroom residence in a full-service condominium. Bathed in southern light, this 1,198-square-foot home has been renovated throughout with refined materials, custom craftsmanship, and modern functionality, while maintaining a spacious and highly livable layout. A welcoming entry foyer with coat closet opens into an expansive living and dining area, where newly added soffits and recessed lighting create a warm, elevated atmosphere. The open layout flows seamlessly into the kitchen and is anchored by a striking custom solid walnut breakfast bar, creating a natural connection between the kitchen and living space. The fully renovated kitchen combines sophisticated design with exceptional functionality, featuring Porcelanosa Krion countertops and backsplash, custom cabinetry, a built-in pantry, pull-out corner storage, and dedicated utensil drawers. A complete suite of Miele appliances includes a built-in refrigerator, range, hood, and dishwasher, complemented by a Marvel wine refrigerator and Sharp drawer microwave. The private primary suite offers a quiet retreat with a custom-built walk-in closet and direct access to a private balcony. The en-suite bathroom is finished with Porcelanosa vanities and Krion sinks, Kohler matte black fixtures, a rain shower, Robern medicine cabinets, and marble tilework. The spacious secondary bedroom features a custom closet system and is served by a second full bathroom with equally refined finishes. Additional upgrades include new HVAC units with integrated UVC sterilization, updated electrical throughout, hardwood flooring, Bosch washer and dryer, matte black Emtek hardware, and a full apartment repaint. For buyers drawn to the refinement and turnkey ease of new development, Residence 7D represents a compelling alternative: exceptional finishes, sophisticated design, and substantial upgrades already completed, without the premium typically associated with purchasing comparable quality in a newly built condominium. Crossing 23rd is a full-service condominium with interiors designed by Andres Escobar, offering 24-hour doorman and concierge service, a fitness center, resident lounge, landscaped garden, and central laundry room. Ideally located just off Park Avenue South, the building is moments from Madison Square Park, Union Square, and downtown Manhattan’s acclaimed dining, shopping, and cultural destinations, with convenient access to the 6, N, R, F, and M subway lines. Note: Listed real estate taxes reflect the current unabated amount. Eligible owner-occupants may qualify for the NYC condominium tax abatement.
