Very comfortable cabin with faultless service. Staff enjoyed what they did and it showed with unexpected extras. Changing ships because of low water is certainly not the fault of Viking and they would very much wished it didn't have to happen. The cruise director made it sound like the low water thing was just happening when we all know it has happened for many cruises this year. Food was above expectations as was the entertainment.
On disembarkation the Viking staff helped us all the way to the airport checkin. I believe that I would have liked more time in Budapest and Vienna but other than that the ports were well planned and touring at each port was made very enjoyable with knowledgeable guides.
The only negative that we encountered was sometimes the dining room put on table cloths that although certainly clean, were stained. They should NEVER put on a stained tablecloth.
Spotlessly clean cabin with attendant who was always very pleasant. Actually quite a bit of space for a river cruise ship. With the river ways so busy we were often docked so that we could not use our balcony as ships piggybacked next to each other sometimes as many as 4-5 side by side.
