We were very pleased with our guide Matthias Stukenbrok. He was a delight to spend the day with. He was very informative and at the same time sensed what we enjoyed. We had our 18 year old grandson with us and it was perfect for all of us. Matthias was able to give us information regarding Lutherstadt Wittenberg as well as facts about Berlin from a much more personal basis. He gave us great tips on navigating the city and getting out to the Olympic Stadium as well as dining ideas that we followed and enjoyed. Thank you very much.
