We just finished a 21 night cruise through Norway and the Baltic on board Koningsdam, our first with HAL, and we were so impressed with Both the beautiful ship, its crew and its entertainment.
Our balcony stateroom was comfortable if a little narrow, with all the amenities needed.
The food on the Lido dining buffet was the best buffet food we've ever had on any cruise line, and the dining room food was also good. Only complaint with th dining room was that the service could be slow so we often ate early to make sure we were free to enjoy the wonderful music at the various menus after dinner.
Clean, very comfortable bed, Everything we needed. Only grouch was the couch, which had removable armrests which fell off if you leaned or put your head on them.
