Description

All showings and open houses are by appointment. Please contact to schedule.

Residence 7B at 4 West 21st Street is an enormous two bedroom with three full baths, washer dryer and central air conditioning in a luxury building with twenty-four hour doorman.

Bathed in soft natural light through oversized windows and wrapped in a rare sense of calm, this mint condition home pairs loft-like volume with the warmth and ease of modern living. Wide plank hardwood floors run throughout the home, while soaring ceilings and pin drop quiet interiors create an atmosphere that feels both expansive and deeply private.

At the center of the residence, an enormous open chef’s kitchen was designed as much for gathering as it was for cooking, seamlessly connecting to the sprawling living and dining spaces. Thoughtfully appointed with abundant storage and exceptional proportions, it is a space equally suited for intimate dinners, slow Sunday mornings, or evenings filled with friends and conversation.

The primary suite offers a true retreat, complete with remarkable closet space and a serene, spa-like bath. The second bedroom is equally generous in scale and flexibility, ideal as a guest room, home office, or both. A private washer and dryer, central air conditioning, and extensive custom storage elevate everyday living with effortless functionality.

Residents of this full service condop enjoy the convenience of a twenty four hour doorman and one of Flatiron’s most coveted locations, moments from Fifth Avenue shopping, Madison Square Park, Whole Foods, Trader Joe’s, celebrated dining, and multiple subway lines.

Sophisticated yet understated, polished yet inviting, Residence 7B is downtown living at its most comfortable and refined.
