If you have been waiting for that special, spacious, pre-war three bedroom apartment, your wait is over --especially if you are looking for a highly desirable established coop.  This corner classic seven room apartment has been thoughtfully reconfigured in a way that adapts to contemporary living, making great use of space and improving the flow.   Entering 11H, you are welcomed into an elegant gallery, a classic feature of all the apartments at 175 Riverside Drive.  The living room takes advantage of its large size to feature a whole wall of handsome bookcases.   The new layout now features an additional passageway connecting the living room and spacious formal dining room.  This passageway functions not only as a perfect place for displaying art, but also creates a sightline through the whole apartment.  The original maids room, kitchen, and butlers pantry have been combined to create a handsome eat-in kitchen with adjacent laundry room and powder room.  The apartment has a separate bedroom wing with three large and well-proportioned bedrooms.  The enormous master bedroom faces south and east with iconic city views and has sun pouring in all day long.  The spa-like en-suite master bathroom has built-in vanity two sinks and large shower. Additionally, the apartment has thru-wall ACs in the living room, two bedrooms, and kitchen.  173-175 Riverside Drive has built a reputation as one of the Upper West Side's most desirable, impeccably maintained, and financially well-established coops.  Designed by famed NYC architect JER Carpenter and built in 1928, the building spans an entire block along Riverside Drive with entrances on 89th and 90th streets. Each side of the building has it's own dedicated staff of doormen and porters who deliver mail and packages to each apartment. There is a live-in super and a terrific maintenance staff that looks after the building. Amenities include a spacious and well-equipped gym, storage units, bike room, two laundry rooms, a game room and a play room.  Sorry, no pied-a-terres or sublets permitted.  50% financing allowed, 2% flip tax.  Please use 90th Street entrance for access to apartment 11H.
