We sailed with the Njord the last week of October and had a very good experience.
The timing was perfect, pure luck on our part, as the autumn leaves had turned and the colors were wonderful, particularly through the Wachau Valley.
VIking staff was fantastic from start to finish, literally. From the moment our flight from US arrived to the time they dropped us at the Nuremberg airport to return home, we were well taken care of. Each staff member seemed to go above the call of duty to be sure we had what we needed and enjoyed our time on board.
The cabins are typically sized. We found we had plenty of storage for two people and our two suitcases worth of clothing. Bathroom is small but good enough.
