Description
Cosmopolitan Condominium – Residence 17F | 145 E 48th Street | $969,000
Sun-Filled Corner 1BR / Jr-4 Layout | 1.5 Baths | 761 SF | Triple Exposure (S/E/N)
Welcome to Residence 17F at The Cosmopolitan—an airy, high-floor corner home in the heart of Midtown East, perfectly positioned between Lexington and Third Avenue. Just moments from Grand Central, the United Nations, and an exceptional mix of restaurants, cafés, and multiple subway lines, this location offers effortless city living with true convenience.
This bright corner residence enjoys three exposures (South, East, and North), bringing in natural light throughout the day. The layout is currently configured as a Junior-4 with a pressure wall in the living room, ideal for a home office, guest area, or flexible additional space. At the buyer’s option, the residence can be restored to a more open, expansive one-bedroom layout.
Notable features include 1.5 bathrooms, generous closet space, and a well-proportioned floor plan that feels larger than its 761 square feet. The Cosmopolitan is a well-maintained, full-service condominium offering 24-hour doorman and concierge services.
A wonderful opportunity to own a bright, adaptable home in one of Manhattan’s most connected neighborhoods.
