Kwame's fantastic tour was a 10 out of 10 experience! I learned more fascinating information about the history of colonialism, links between slavery and capitalism, and the continuous presence of Black people in Europe in those 2 hours than I might have learned over the following decade on my own.
Kwame is sharp, engaging, knowledgeable, and very thoughtful about the locations, content, and storytelling he provides during the tour. If you are at all curious about this tour, it is a "can't miss" opportunity that is likely be the highlight of your visit to Madrid.
