If you've ever gotten off the subway at 72nd Street and Broadway, you've probably seen a tall, French Second Empire building and wondered: “What is this unusually elegant building doing here on the Upper West Side?” Well, that building is The Ansonia, and it is a crowning jewel in Manhattan luxury and architecture. At 2109 Broadway, The Ansonia's location can only be described as prime, and its detailed and historic façade is a fusion of Parisian design and a New York-style need for height. Originally a hotel, The Ansonia is now a pre-war condominium conversion with traces of its past, but still one of the more recognizable structures in Manhattan.   With 425 condominiums, The Ansonia is rather large indeed, as is the variety of residences available, ranging from studio to four-bedroom apartments. All condos for sale, however, retain elements of hotel living and are home to some of Manhattan's most exquisite residential spaces. Circular foyers are not an usual sight; neither are French sconces, chandeliers, and ground-level colonnades. Each residence at The Ansonia has a small, private balcony due to light shafts in the façade, while granite counters, skylights, and circular windows accent some of the quirkier floor plans available in a Manhattan condominium.   The Ansonia has not forgotten its hotel past with a number of amenities that make living at 2109 Broadway the definition of luxury. A rooftop terrace gives residents a great place to host gatherings or to enjoy one of the Upper West Side's best panoramas. The Ansonia's private fitness center has all the equipment necessary for a thorough workout, while personal parking is also available. In addition, there is a full-time doorman and individual storage. Simply put, The Ansonia is one of Manhattan's most impressive condominiums, so why not make 2109 Broadway your new address?
