Confused and not updated guide, it seems that the authors have not revised their previous edition and simply changed the date. An example among others: the last edition which is presented in the Museum of Modern Art (permanent exhibition) has no relation to what is described in the guide. This is true for many places of exhibitions (some closed etc.)
Very low for hotels, to ask whether the authors go there. Data bus & tram confused circulations almost forgotten. The authors have not assimilated the transport plan reflecting the former East / West division.
The authors confuse Potsdam and Potsdamer Platz, in short not read and probably mistranslated.
it would take several days of reading to understand the write logic and begin to eliminate errors, which is done by trial and error and thus encroaches on the pleasures of the holiday, pretty useless book but not unpleasant to read.
