This newly renovated one bedroom (with a separate den or sleeping area) and two bathroom duplex condo with a huge patio is a truly rare find on the Upper East Side. Nothing was overlooked in this brand new high-end renovation.  The upper level features a grand living space large enough for separate dining and an open kitchen plan with custom cabinetry and top of the line Bertazzoni and Miele appliances.   The living room leads to your own 444 square foot back yard which has been finished with blue stone tiling and cedar fencing.  The generously sized master bedroom is also on the upper level as well as a completely renovated master bathroom outfitted with the best fixtures and finishes.  The lower level can be used as a den/media room or as a separate sleeping area.  There is an additional fully renovated full bath conveniently located on the the lower level. There are brand new gleaming wood floors throughout the apartment and a split AC system on both levels along with new doors and windows leading to the patio.  The Gemstone Condominium is an intimate prewar brownstone building conveniently located near the new 2nd Avenue and 86th Street subway stop. The building is located on a quiet tree lined street with convenient access to transportation, Whole Foods Market on 88th Street, great restaurants, night life, culture, and both Carl Schurz and Central Park.
