By far this 7 hour walking tour was the best way to see and learn about Buenos Aires. Jessica is an amazing guide. Full of knowledge and charm. She took us places that we would of never went by ourselves.. We had a conversation with other passengers from our cruise, that took an excursion offered by cruise line and were told that it was a terrible choice. WE on other hand had a great fun time.. I felt that I can use another 7 hours, city is wonderful and private walking tour is the way to go.. Thanks you so much!!
