This apartment is long and narrow, but it’s also got a ton of square feet and some inventive design to make for a pretty nice pad. Located at the Lower East Side condo 71 Ludlow Street, it boasts 1,646 square feet, three bedrooms, and a $2.395 million price tag. (It last sold in 2013 for $1.65 million.) A curvy kitchen dominates the middle of the open space, while bedrooms are placed on either side. And surprisingly, for a railroad layout, the apartment boasts three exposures to bring in light.
