We embarked in Vienna heading for Nuremberg on Amadeus Queen. Because of the low water levels on the Danube we changed ship to the Amadeus Elegant. It was like transferring from a 5 star hotel to a backpackers room with an ensuite.
We lost our spacious room with walk-in wardrobe and refigerator to a very small room. There was little hanging space. We could only store one suitcase under the bed as there was not enough room between the bed and the wall to roll the suitcase under the bed. No refigerator. I complained about the refrigerator and was given a 6" x 8" cooler box. Fair enough, I only wanted it for medication. Carpet was very worn. Ceiling and walls needed painting.
But at least the crew was very friendly and obliging.
