Sara Frisk never thought about traveling to Mexico City until a stranger named Pilar Muñoz invited her. Ms. Muñoz, a publicist for designers, lives in a 4,300-square-foot penthouse apartment with glass walls and luscious green views. The home has richly grained wood floors, trim modern sofas and a kitchen island you could sacrifice an ox on.
“If I was going to Mexico, I wanted to be on the water, but that house is completely amazing,” said Ms. Frisk, a graphic designer and design consultant in the West Town neighborhood of Chicago.
