Donna Keena stated, “As the name Ethos implies – Sound Development has created a place to ‘Live Simple. Live Beautifully.’ There is no other property that can compare with the amenities and location of Ethos Kelsey. The view from the seventh-floor rooftop pool to the Manhattan skyline is exceptional. And Belleville’s charm is rooted in its rich history, vibrant local culture, great schools, and beloved landmarks like the iconic Belmont Tavern and the scenic cherry blossoms. Ethos Kelsey residents will be enamored of their home and their town.”
Highlights of the upscale amenities include Belleville’s first and only rooftop pool—complete with private cabanas, grilling stations, and views of the New York City skyline— two Zoom workspaces, overnight guest suites, several lounges both indoor and outdoor, a state-of-the-art fitness center, pet spa, dog run, game room with billiards, dedicated package/cold storage and mail reception areas, bike storage and covered parking.
Dubbed the Cherry Blossom capital as it rivals Washington, DC in the spring, Belleville is seeing transformative changes that continue to blend suburban comfort with ease of accessibility to New York City and Newark.
