Nikolaiviertel

1h round trip starting and ending by the spree at friedrichstrasse. Punctual and nice way to see Berlin.

There was no guide, but instead the explanation was recorded and that way we didn't feel any engagement with what was being said. Apart from that the boat was nice and the bathroom was clean.

It was a great tour, most of the monuments of Berlin seen in an hour. While it was a high sunny day, more umbrellas would have been better.
