We were disappointed with the size of the room. It was REALLY small. Our room 5108 was supposed to be a 147 sq. ft. "Superior Inside" Stateroom, Category JJ. While they categorize 5108 as a 147 sq. ft., "Superior Inside" on ncl.com, I believe it is really only 121 sq. ft.—the same size as the Category N "Inside" (non-Superior) Staterooms, such as Cabins 5101, 8114, 8315. We were disappointed that the deck plans on ncl.com were not completely accurate and that room 5108 is mis-categorized as a 147 sq. ft. "Superior Inside", when it should be displayed as a 121 sq. ft. "Inside" Stateroom.
There was barely any room to walk, there was one shelf and three tiny drawers in the closet under the safe, the closet itself was small with only 2 compartments versus 3 on Carnival, but there were plenty of hangers.
On a good note, Room 5108 is right behind the elevator and we heard absolutely no noise.
