Return to the Grandeur of Yesteryear and enter this gracious 4 bedroom, 2.5 bathroom home in one of the Upper West Side's most coveted white glove Cooperatives.  The layout of this home is truly exceptional - a unique and expansive entertaining space spanning the full width of the building with both northern and southern exposures is reminiscent of a time gone by.   One enters an oversized yet gracious foyer that joins the enormous formal living room and equally large separate formal dining room.  A large eat-in kitchen is perfectly situated to service the grand entertaining space.  The split living quarters allow for a flexible layout.  Off to the right down a corridor are three bedrooms including a choice of a master bedroom facing south.  To the left of the foyer is a large bedroom complete with bath en suite and could be considered the master or fourth bedroom.  High ceilings, hardwood floors and gorgeous light complete this home.  Kitchen and baths in original condition.  Built in 1915, 310 West 86th has a 24-hour doorman, a live-in superintendent, porter staff, common storage, bike room and central laundry facilities.
