Overall it was good. We probably enjoyed the hop on hop off bus more. The ticket is an issue. We bought in advance but realized what although we had a QR code we still had to join a queue to change for a ticket. This means it didn't help buying in advance. Others that turned up with ore buying got on first. The biggest bug bear was a group of about 6 people went to board without queing but they were sent to desk to change which meant queing like the rest of us same purchasing people. But one of the group stayed at gate. Somehow!!!! The guy at the check in reserved a whole table for them. How was that allowed I wonder. We then even though we queued struggled to get a to seat upstairs but they somehow even though way behind us got preferred treatment. Not good!. The service by the young lady was absolutely excellent. Great service great memory.

The boat was clean and the crew was top notch. We had a storm pop up on us and we had to ditch the top deck for the inner deck for about 20 minutes, but when the storm was over, the deck hand was up there drying everything off. The commentary was just enough - not too much and not too little. The scenery was amazing and we got to see so much more than we would have with only a walking tour.

Relaxing and interesting floating view of Berlin with good commentary (audio guide). You get a different sense of Berlin than you would get as a tourist on land. I had signed up for what I thought was the East Side Boat Cruise, but this turned out to be the standard 2.5 hour boat cruise. Food service was limited, but the experience was fun.
