Tour was ok, but there aren't any well defined route stops on the street - so there's no signage to indicate where the bus stops. I hopped off at one stop, only for the next bus to go right past me when I wanted to return?! I had to physically waive to stop the driver of the next bus to indicate I wanted to hop back on...if they just had clearly marked signage and stops it would be a lot better.
The paper voucher was accepted and a ticket was issued. We stopped at the East Side gallery which was worth seeing all the varied artwork. We could have done with more information and directions as to where to find the trendy district of Kreuzberg as i think we must have walked past it. Our final stop was the Jewish Museum which was well worth a visit but allow 3 hours or more as there is a lot to see and read.
