The view from my room (15th floor) faced an office building, so I had no view of the Rockefeller Plaza or any possible tourist site. To reach the 15th floor, it is also necessary to take a separate elevator from the 14th floor to the 15th floor, so it takes slightly longer. Also, the free purified water is not available on the 15th floor, so you need to go down to the 14th. Again, only minor inconveniences -- overall stay was great.
As many others have mentioned, the location of the hotel is the top selling point -- Rockefeller Plaza is less than a minute away. 5th avenue is just at the end of the block, also a minute away. Staff is very friendly and recommend restaurants, hold luggage, and book taxis.
