I took a tour of this building a few months back and the floorplan differentiation is the deciding factor in window placement, (I even asked that question myself

). The above floorplan reminds me of the units found at each of the first two setbacks of the buildings, the balconies are huge, as each tenant recieves the entire width and half the length of each setback (two units), the penthouse balconies are even larger and offered some amazing views of the city (sorry, my account ran out on the pics I posted of some interiors and the aforementioned balconies but they were quite impressive views).
