We did 2 tours with Nani and couldn’t have been happier. He took us to areas less visited by lots of tours. This was our second visit to this city and we felt like hardly anything was a repeat of areas we had been to on the previous trips. He was knowledgeable about the city, its history and the local culture. We also learned a lot about Argentinian culture, and specifically about Polo. He entertained us with lots of stories and kept us engaged. He also helped us secure dinner reservation. Would recommend him if you are looking for a knowledgeable guide.
