It’s Free to Look: 151 East 58th Street

Whip out the binoculars! This One Beacon Court rental is an ideal perch to spy on neighbors you never even knew you had.

Up on the 32nd floor of a midtown tower, with south and east views, the apartment offers exceptional visual access to at least half of the borough of Manhattan and probably some of Brooklyn. Voyeurs will especially appreciate the 800-square-foot terrace, with padded benches for kneeling with a telescope.

Windows line the apartment's walls. The network of glass is so extensive, in fact, that, try as you might, you almost can't avoid a breathtaking view. The Douglas Elliman listing advertises "huge walk-in closets," which might be the only place to hide.

If neighbors get wise to your gazing, you can always duck out when the lease is up. And $39,000 a month almost sounds affordable, especially when you consider that it's about the same price as a dinner at Le Cirque restaurant downstairs. —William Alden
