The Ansonia, the Upper West Side wedding cake of a building at 73rd and Broadway, was built as a grand hotel by one very eccentric copper heir, who went so far as to install a farm on the roof. Now converted into apartments, the Beaux-Arts co-op has done away with the farm and instead has focused on commanding many millions of dollars for its intricately detailed large apartments. Still, there are thrifty ways to sneak inside these storied walls. This studio, measuring just 300 square feet, is up for lease for $1,850 per month. That's not exactly chump change, especially considering the awkward layout, but the updated kitchen is pretty substantial, though not in keeping with the style. Is this place simply too small or does the tony address make it all worthwhile?
