super interesting and knowledgable, great way to see Buda and learn about the history as well as current social issues
very nice guy, but not the best tour guide. talked a lot about Space Invaders and random things that had nothing to do with Paris, without providing much interesting information on Montmartre. Went on a lot of tangents, However, he did give some great recommendations for local restaurants and how to not get scammed at Air B N B's.
Thierry is a super interesting and kind guru. He was full of information and made the tour lively and exciting. He took us to less well known places, as well as locations that one might pass everyday without knowing the history that happened there. I really enjoyed getting to know him and learned a lot on the tour.
