Often tour guides are a hit and miss. Even those you find highly ranked on TA sometimes disappoint after going around town with them. Sure a lot have deep knowledge on the subject matter but I think it's another story to be both knowledgeable, entertaining and have the tour group interested at the same time.
This was Kevin to us. He was highly knowledgeable on Nuremberg's WWII history and yet he always caught our attention as he explained the history of the sites we were visiting throughout the tour. I enjoy WWII history a lot and I thought he was a great source of information. However, what I think makes things even better was that my wife enjoyed his tour even if she wasn't half as interested as I was on WWII. I think that says a lot about Kevin!
We both highly recommend Kevin for your tours around Nuremberg. In fact, I hope Kevin could do the same for Munich and Berlin. I think he would do an awesome job for those two other cities as well.
Thanks Kevin for your enthusiasm and more power to you!
