We spent two glorious weeks sailing from Amsterdam to Vienna on the River Duchess. The ship was beautifully appointed from our lovely state room to the public common areas such as the lounge and formal dining room. The service was top notch in every way from housekeeping to the serving staff in the dining room. Our cruise director Heiner was a gentleman's gentleman and saw to every detail of our cruise experience both on and off the ship. The walking tours were interesting and the guides were very knowledgeable and charming. Internet access was spotty but not a deal breaker. We salute Uniworld for a job well done!
