We were on deck 11 (11156) on the NCL Jewel(same plan as the Jade) in aft cabin middle of the rear end. We too were just under the outdoor cafe (deck 12). You will get some noise, mostly from chairs being moved around, on the metal flooring; but we found this was during peak periods only. You should have no problem in the late evening hours as the outdoor cafe closes about 9:00 PM or earlier. On the Jade, the Italian rest (Mama's) is on deck 12 also. If Mama's is full, they will use the outdoor cafe area for seating. If your in 11156 or 11656 expect a small outside balcony. It is a balcony, but I would consider it tight space. Dramatic views, yes. My wife had booked us on the NCL Star aft cabin, and had asked to change to a port or starboard balcony. Looking over the balcony on aft Deck 11, was pretty scary to me.
