We went with Andreas. It was a great tour with a lot of humor. We sat a part of the tour upstairs: I recommend a scarf and hat, it was very windy despite 17°. We sat down for the rest of the tour and were still able to see and enjoy everything without the wind.

It was a nice tour where you can learn a lot about Hamburg.. if you understand German :) The presentation in German language was extremely loud, in the background, which covered the sound of the guide in our headphones. So practically if you don't understand German, you will not get much from your headphones anyway. We've participated in other tours before across Europe and it's the first time we had this issue. Normally each person had their own headphones with their selected language, regardless the country where the tour is taking place. This was different. But besides this, the tour was ok and I recommend it if your are there for a short stay, because there are a lot of beautiful places in Hamburg to see :)

Good in general

The hop on and off bus personnel told me I can't use a mobile ticket. If I'm travelling, where am I supposed to find a printer to print the tickets? This highly discourages people from buying online. There was another operator who let me on the bus to go to main station to change my ticket into a paper form. This is such a hassle. Hence why I gave it a minus 1 star. I also found out later that it's cheaper to buy in person than to buy online. This highly discourages me to purchase online again for this tour. Despite that, going around town was good. I wish I did this on the first day I was here so that I know what was around town to explore further. Since I did it mid way, I already went to several places that the bus was stopping at. It wasn't as appealing. It is overall, a great method to see the city
