Looks like you were right below Deck 15 on Deck 14? Was it loud? Were you under Galley? We almost booked 14 102A (102 A and Z are slightly larger terraces) but chickened out and moved our reservation to Deck 12!
We were 14098Z. During the day you could hear carts roll around from time to time. We didn’t really have any issues at night, and I’m a pretty light sleeper!
