We had not been to Berlin or Prague, and the price was excellent!
My husband and I are very interested in history. Each port had such significance to us, and the guides were all very knowledgeable, and were able to give us their perspective of the area and events. They were able to bring alive the events of 70 years ago.
The art museums were of particular interest also. Our guide was able to give is wonderful and unhurried tours. We didn't just see the most popular paintings, but those that had particular impact on society and art history.
We ended up on the Clara Schumann, as there were several other ship changes due to the water level. This was an older very small ship with very small staterooms (98 passengers). They still had actual keys. I believe this was its last cruise.
However, everything was immaculate!
