Our cruise on Norwegian Star departed Barcelona 4/23/22. We were very excited as we upgraded to an aft penthouse balcony suite on the 8th deck. The first night was fine. Unfortunately, the following 7 nights at 10 pm the vibration from the base being played in the lounge shook our suite floor. The music typically ended at 1 a.m. We were not aware that the 8th deck aft staterooms were above the Bliss lounge, which apparently had no sound proofing. We brought the noise issue to the attention of our concierge as well as the General Manager with absolutely no resolution. Our concierge's solution was to have us sleep in another stateroom then return to our suite during the day…Really! We left 2 complaint letters with the General Manager who apparently was too busy to respond to either letter. We contacted Norwegian and their solution was to give us a token credit on a future cruise. I loved Norwegian until this last cruise, now they are on the do not sail with Norwegian list as far as we are concerned. There are certainly other cruise options. Based on our experience pick another cruise line who cares about the comfort of their passengers.
