We were on the Main level in the Aft section. We had significant engine noise. This was not bothersome, but actually helped me sleep as I usually sleep with a fan. On our last night, as we were returning to New Orleans, the noise sounded like we were scraping the bottom of the river bed - so that wasn't very relaxing. I was impressed with the room size, level of comfort for the bed and pillows. We had ample room for all of our belongings and the entire floor was quiet, clean and comfortable.
