My family of 3 adults and 2 teenagers just completed a 2-day trip in Venice which included the Art and Architecture tour and the Canarregio Neighborhood tour with Context. I booked both as private tours. They were both wonderful. Both guides were very knowledgeable, and spoke very clear English. They were both prompt, and got to know a little about our group and interests before starting the tours. I would caution anyone booking these tours that there is a lot of walking! 3+ hours is a lot of time to be on your feet. My group is very fit and active, and we were very tired at the end. If you are in reasonably good shape, though, this is the best way to see Venice. The tours take you away from the crowds, and show you a side of Venice that I doubt most tourists ever see. You will still see the major attractions, but also the less visited ones.
