I've joined Spreesprecher on their boat trip twice now and I must say that both times it turned out to be the most unconventional experience. Even though the tour passes by all the major (tourist-) attractions of Berlin, I recommend it to locals as well as (english and/or german speaking) visitors of the city. Since our guide delightfully combined historical facts about the city and its history with current daily events, every trip is an unique adventure. In times where most guides are just reeling their prepared speech off (or one is even forced to listen to an audio recording) the subtle and unusually smart humor of our guide made both trips not only very informative but also quite funny... I advise everyone to do it and then do it again and again! I loved it. read more
