Paradise inside out.   Authentic one bedroom Penthouse with windowed kitchen and  bath, high ceilings and a living room with three exposures.  Sliding glass doors lead to wrap terrace with open views North and West to the Hudson River.   Protection from the elements extends the use of the terrace by many months.  A creative eye and green thumb will transform this gem into a zen retreat.  Perfect quiet and private get-a-way, the property is one flight up from passenger elevator landing but service elevator does access the floor.  Pre-war, doorman building with private basement storage, laundry and bike room.  On the corner of 72nd Street and West End  close to both Riverside and Central Park, Lincoln Center, shopping, transport and the best of the Upper West Side.
