    Luxury furnished rentals in Mountainside, NJ

    Mountainside is a small, leafy Union County borough that backs onto the Watchung Reservation, giving it a quieter, more natural feel than its busier neighbors. We place clients in furnished Mountainside homes for medical stays, relocations and renovations.

    Living in Mountainside

    The Watchung Reservation, the largest park in Union County, forms the borough's western edge, and the Trailside Nature and Science Center sits within it. Echo Lake Park lies along the eastern side, and Children's Specialized Hospital is based in town.

    Furnished luxury homes in Mountainside

    Expect spacious Colonials, ranches and contemporary homes on wooded lots, many updated with modern kitchens and backyard space. Homes near the reservation offer a sense of seclusion that is rare this close to Route 22.

    Getting around

    Mountainside has no train station, so commuters typically drive about 5 to 10 minutes to Westfield or about 15 minutes to Summit for trains. Route 22 runs through the borough, Route 78 is close, and Newark Liberty is about 20 to 25 minutes away.

    Who we place here

    Families with children in care at Children's Specialized Hospital who need a home nearby, executives working along the Route 22 and 78 corridors, and local families rebuilding after storm or water damage.
