Our experience with Andy's Regensburg tour was nothing short of FANTASTIC! Firstly, Andy is just such a friendly guy - smiling and so welcoming always and you can see he loves what he is doing. His knowledge of Regensburg, it's history and vast tradition is second to none - you can see how passionate he is about the place. The ride itself on the unique rickshaw is an experience in itself - one of a kind, super comfy, even has amazing lights and speakers for a little background entertainment. The different stops on the way during the tour a very well planned and can even be customised a bit based on your interests. He'll also keep you well hydrated, the Bavarian way! ;-)
Overall an easy 5/5 if I had to rate this - highly recommended!
P.S. - As a bonus - his English is great so communicating is simple and straightforward, even if you are not a local - and that's a highly underestimated plus too!
