Definitely not "luxe" on our ship, the Lofoten (now retired). It had 100 pax, a little crane for some cargo, day passengers. There were only two other 'Americans' which we loved. English, German, Aussies and more.
The cabin was super small. We couldn't both stand up at the same time. The shower had no 'curb' so when the water was rough one day/night the water would run across the bathroom floor. We put bathroom 'stuff' in a cardboard box and set it on the toilet when we were in the shower. Loved every minute of it.
Now need to do the fjords.
