The south-facing primary bedroom enjoys beautiful East River views, a generously sized walk-in closet, and a renovated en-suite bathroom.

Additional highlights include custom built-ins, a wood-burning fireplace, warm hardwood floors, an integrated Lutron lighting system with smart switches, and custom millwork. In-unit washer/dryer permitted with board approval. Southgate is a pre-war Emory Roth building built by Bing and Bing development.

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
