Superior rooms are definitely a more western style room. They're very luxurious and perhaps my favorite for any FS Marriott property.

That said, the 38th floor is a busy floor with the lounge and other services. Noise might be a problem, though highly unlikely. If you're uncomfortable with heights, rooms up in the 50s will probably not be to your liking, though even at 38 it might not work for some.
