We have sailed NCL before (not the Jewell) and they were decent trips, but this old piece of scrap metal built in aug 2005 is in very poor condition, all the floors need to be change, the stateroom carpets are fitly, 10th floor in around cabin 10078 had serious sewage issues so every day we had that lovely aroma to walk by.
Others also have water back up, and NCL does not believe in maintenance, another example would be the elevators, the bells and up down Arrows don't work on most floors,
Worst food smallest food court of any ships around, never any place to sit!
Needs new carpets, ours were fitly
