HIGHLY RECOMMEND! This walking tour was one of the best I have done in the U.S. and abroad. My husband and I took a 4.5 hour private tour with David through Lower Manhattan, Battery Park, Wall Street, World Trade Center site, China Town, Little Italy, The Bowery, Chelsea Market... David customized the tour to our requests as we went along and was knowledgeable, easy going, and friendly. It felt like walking with a friend through NYC! He was sharing information, we both were sharing stories and things we liked to do, read, watch. We stopped to have coffee to warm up on a cold December day, BRRRR!!! David shared titles of books he liked to read (How The Other Half Lives by Jacob Riis) and movies he liked to watch (The Gangs of New York, Martin Scorsese, 2002.) We learned "a lot" about the history of NYC, became very familiar with Lower Manhattan and ended the day feeling well-exercised, happy and a little more "streetwise!" :O)
