What a fantastic tour through La Lagunilla Market, Gran Hotel Cuidad de México, Palacio Nacional/Zócalo/Roma Norte! Antonio S. was knowledgeable, considerate and helpful. He provided wonderful history/local info on the areas that we visited. He is articulate and professional. At our request, he was thoughtful to find an authentic heladeria in Roma Norte for us to get our gelato fix. What a tasty and memorable stop! We highly recommend Antonio S. for tours around Mexico City.
