On all 3 cruises we've been on Deck 6 - rooms 6538 & 6536. Far enough away from major cross traffic that noise wasn't a problem, easy to grab the forward stairs to come and go (those are usually less busy than the midship set), and generally on the "best" side of the ship when docked - ie: port side except at CC when we faced the lagoon.
wW recently were in 6072 and 6074 and liked the location,especially midship.
However if I were to do it again i would do deck 5. very convenient to kids club,theaters,lobby and restaurants. Also deck 5 seemed very quiet,which is nice.
