By far and large our most expensive listing, this four-story townhouse sits princely on the 12th floor. Of course, it has a gigantic, private roof deck. Of course, there's a private elevator. Of course, the ceiling in the den is brilliantly coffered. All surfaces, whether marble, tile or hardwood, gleam with an iridescent shine. One might scoff at the paltry three bedrooms and 4.5 baths, but their lavish treatment makes it worth the exorbitant, monthly price tag—if you're a millionaire.
