In my opinion, Free tour is a great concept especially for traveler with limited budget like me, because normal tour will cost you 10-15 euros while in this tour you can pay as much as you can afford, and Berlin being the city with such a dramatic and important history in the past is such a perfect place to join the tour as you get to know all the history! Yes, you can always walk by yourself to all the places they taking us, but, the stories that makes it different. And with this concept, the tour guide also will make sure they bring good one or people wont give them tips.

It's great if you only have a few days in Berlin and want to get a good overview of the sights and history, which there is a lot to learn. The guides are fun and knowledgeable and so inexpensive. Great whether or not you are on a budget. The bike tour (not free) are also a fun option if you want to go around by bicycle.

Very nice tour around the city, the guides are very cool and they know a lot about the city history and some funny things. In Berlin you realy don't need to pay for a Stadtrundfahren (with bus), it's realy better to go with the Berlin Free tour. They have a lot of time options and languages.

Great tours with very knowledgable guides that bring the history of Berlin to life with a few jokes along the way. Always love the free tours as they work on a tips basis which means they work really hard for their money rather than tours you pay for that are often not as good.

I was fortunate enough to have a well-travelled fellow New Zealander guide me around. The tour was full of laughter and the people were just amazing. Berlin is a city rich in culture and history. If one doesn't know where to start, this is definitely the place.
