The MS Lofoten is a lovely old ship (48 years old). The key word here is "old" -- it creaks and rattles a bit, it is faded in parts, it has no stabilisers, it has "no" many things and that is why people choose it. The crew work hard at maintaining it. We found them cleaning the outside windows at 11 pm when we were in one port, and the cleaner on board seemed to be polishing the brass and sweeping spotless floors continuously. Heating on the ship was a bit erratic -- we were either far too hot or a little cold, again it is an old ship thing.
The Lofoten is small and that is its greatest asset because provided you make an effort to join in, then you rapidly become part of its small family. I think that in high season with some 350 people on board, it might feel a bit over crowded and certainly the forward lounges (on two levels) could not house everyone if they wanted to see things from the front. There were 16 full-trip passengers plus anything up to 29 short trip port to port passengers and 34 crew - so there was plenty of space.
Overall, the cabins are ok. We were lucky with our one which was excellent, those down in the bowels of the ship might feel a bit cramped and some might be noisy but I have no means of comparing these cabins to those on the larger Hurtigruten ships -- they might offer exactly the same experience and this might not be a small ship thing. I did go on a few of the larger ships whilst we were both in port and they were immaculately and tastefully decorated.
Cabin 304 - larger than most, two beds, window which opens onto a quiet external gangway and then the sea. About 11m2 plus a toilet/shower of 3 m2.
Cabin 220 - small, two bunk beds, above waterline, porthole which is closed with a metal flap during winter for safety reasons, engine noise is slightly noticeable
Cabin 302 - single bed, wash basin, window which opens onto a quiet external gangway and then the sea, toilet and shower close by.
