It feels separate from the chaos of Manhattan, offering pristine streets, parks, and river views. High-rise luxury living is the standard. Most buildings are full-service with doormen and gyms. It is one of the greenest neighborhoods (literally and LEED-certified). Quiet, family-oriented, and upscale. It's a favorite for finance professionals working in FiDi and families seeking safety and space. While physically west, it's connected via pedestrian bridges to the 1/4/5/R/W trains in FiDi. Ferries are also a great option. The Esplanade is world-class. Rockefeller Park and Teardrop Park are pristine. Brookfield Place offers high-end shopping. Best for families, dog owners, and those prioritizing quiet and water views. - [Battery Park City Guide](https://realestaterebatesnewyork.com/neighborhoods/new-york-city/manhattan/battery-park-city) - [Browse Battery Park City Residences](https://realestaterebatesnewyork.com/buy/newyorkcity/manhattan/battery-park-city-manhattan) - [All Neighborhoods](https://realestaterebatesnewyork.com/neighborhoods) ## Frequently Asked Questions ### Where is 21 South End Avenue?
