Went with a friend early on Sunday morning (10am tour) and had only two other people on the tour with us. Our tour guide, Jackie, was amazing. Highly educated about art (PhD student) and very knowledgeable about the artists, and the street art scene in general. She welcomed questions and gave really thoughtful insights to the historical and social context to what we were looking at. Pace was very easy going. A really fun, interesting and educational couple of hours!
