We had this tour with Andrew, and we enjoyed it a lot. Frankly, for me it was the best tour ever. Andrew has great mastery on the history of Russia and Moscow in particular, and his stories are insightful, surprising and well documented. He helped us make sense of the city well beyond what we could achieve on our own. He is also a very authentic storyteller, and, although we did not always agree with his historical perspectives, we greatly appreciated the opportunity to understand better his point of view. We traveled with two boys, aged 11 and 12, who enjoyed the tour a lot - especially all the fun stories and insights about Moscow's buildings and its historical personalities, and the details about last century's wars. The only improvement could be, for larger groups, a way to hear better the guide at times the boys said they could not hear everything. As adults, we managed to hear everything fine. In brief, we strongly recommend the tour.
