The Walking Tour of Secret Sites and Hidden Gems, was absolutely wonderful!! Hannah, our excellent guide, was cheerful, courteous, and very informative. She also had a very good sense of humor, and we loved the places she shared with our small group! Unlike most bus tours, where you really don't get to gain a flavor of the place you are visiting, Hannah made sure to cover many bases for our group, and we all very much enjoyed her lively and entertaining narrative of what we were seeing, and what hidden gem would be next up on our walk. For my wife and I, THIS is the proper way to see and enjoy Paris, and we would highly recommend this tour to any and all folks who wish to really get a glimpse into the real Paris, with the small caveat that these folks be fit enough to actually get out and walk. If walking is your game, then by all means, add this tour to your trip plans. You will not be disappointed!! And, if by happenstance, you get Hannah as your guide, we know that your experience will mirror ours, and that you will be very glad you were able to see Paris the way it should be seen!! Thank you, Hannah, and thank you, Viator, for this superb tour!!! Cheers and God Bless! P.S. For you Harry Potter fans, be prepared for a very enjoyable surprise!!!!
