It was useful having the app and being able to see the buses coming and being able to track the bus while you are on it and know when your stop is coming. The B route is different to the one published that is on the website. It is longer and takes in the things that it says but also other things to the north of the centre like Gedenkstatte Berliner Mauer. The commentary is not particularly good and the attempt at humour is very poor and tedious. I turned it off for some sections of the ride.

Good way to get around and get a base feel for Berlin

We managed to get through both tours A and B on the one day so we could figure out where to focus on the next day as we had a 48 hr ticket. The buses were good but the constant stopping for breaks (usually smoke breaks by drivers) was annoying. The commentary was only so so and didn’t often match up to where we were. What was good was the frequency.

good overview of the City

though delayed by the Berlin Marathon and having to use many detours we still were able to get a good overview of the City - using the two routes allowed us to see different areas; transfers between routes was pretty quick. We had a great experience by the representative at Checkpoint Charlie (he was very helpful when we were experiencing a delay caused by the Marathon). The only thing we were not expecting were the delays because of driver breaks; 20 - 30 minutes.
