With waterfront views of the Manhattan skyline and a compact grid packed with outdoor cafes, bars, and shops, Hoboken draws its fair share of upper crust commuters. Many of them take the city's rail or ferry lines into New York City. But when they're at home, residents of this Hudson River locale enjoy park space, beaches, and a waterside walkway teeming with people who've left their cars behind. Space constraints mean single-family houses are scarce, but historic brownstones and row homes offer plenty of upscale amenities.
