Situated in a gracious prewar elevator townhouse, this coop is on one of the loveliest and most coveted tree-lined streets (between Park and Madison Avenues) in the heart of the Upper East Side.  This chic and ultra-cool Penthouse two bedroom, two bathroom duplex home is complete with an exquisitely landscaped private terrace.  On the first floor, there is a generously proportioned living room with wood burning fireplace, a well appointed galley kitchen with top of the line appliances, a beautifully finished full bathroom, and a flexible second bedroom/den/home office.  The second floor is home to the master bedroom with designer master bath en suite and access to the sun drenched planted terrace.  This extraordinary home has its own washer/dryer, through the wall A/C, painted original oak floors, generous closets, and a video intercom system.  This non-doorman townhouse, built in 1910, sits at the center of the most elegant square mile in Manhattan, and just a block and a half away from Central Park. Fabulous shopping, museums, and fine dining are at your doorstep. The building offers individual storage units for each resident, a full-time Super, and additional laundry in the basement. Pied-a-terres, pets, co-purchasers, and guarantors are allowed.  Whether you are looking for your primary residence or the perfect pied a terre, you have found your new oasis.
