The penthouse at 66 Madison Avenue is one of those unusual apartments that resembles nothing so much as a charming cabin in the sky, surrounded by 700 square feet of outdoor terrace space. This 1,100-square-foot one-bedroom co-op–located in the building's original rooftop machine room–is perched atop a 1918 Beaux Arts building in the popular Nomad neighborhood. 6sqft featured the rooftop aerie when the previous owner, designer and fashion PR exec Leslie Klotz, listed it for $2,450,000 in 2016; it sold for $2,260,000 in early 2017. House Beautiful called the light-filled home, now asking $2,500,000, "a wonderful mashup of Manhattan and Montmartre."
