Having been on several cruises, and reading adverse comments about Ambience, we were apprehensive. My wife and I thoroughly enjoyed our Norway cruise. We had a spacious outside cabin, that had numerous drawers and wardrobe. The mattress was comfortable, and the shower was superb.
The entertainment with very very good singers and dancers, and was better than most of the known cruise ships we have been on. Also they had a funny well-acted farce, I have never seen on other cruises.
Food again is hit and miss as to your liking, but its the same as other cruises. Its best to use the sit down restaurants, as their buffet (Borough Market) is too small and gets crowded, so we avoided, except for the afternoon scones or doughnuts. The Boroughs food selection was good and varied, if you had the patience to queue.
