Ambition Dluxe Suite Deck 8 or 7

[60s Wombat]

Hi - thinking of booking Dlux Suite on Ambition.  Can I please ask anyone who has experience, are those on Deck 7 the same size as Deck 8?.  Or are there any other differences? Also as cabins on Deck 7 are above the Deck 6 restaraunt does this mean they are noisy?. Also, as I note the bed in this grade can't be separated, I presume it is easy just to get the sofa bed made up at evening turn down?.  Many thanks.
