I can only confirm what has been said already. Much quieter than downstairs, the storage bins are smaller (so either try to put under the seat in front of you or in the cupboard at the back, but note that some of the seats up there in Economy have some sort of equipment boxes under them, restricting space for bags), you get off before the rest of Economy downstairs, and there's quite a big area between Economy and Premium to stand around to stretch your legs.
