I haven't stayed in this room or any that was in a similar location, but from looking at the deck plans, I can make a couple of observations.
It looks like they configured the cabins in that area so they could get the additional ones along the middle row.
The only thing I see that could be a problem is that you would have three other cabins along the exterior walls of that one. In the worst case, you could have noise from the inhabitants of those adjoining cabins. If that type of noise bothers you, you might consider trying to change your cabin assignment.
I do like deck 6 for being centrally located. It isn't far from the clubs, shows, restaurants, and kid's areas on decks 3, 4 and 5. It also isn't really far from deck 9.
In this location, you would have passenger cabins below on deck 5 and above on deck 7, so no nightclubs really close.
hope that helps
