Bart was great. Quizzed us on our interest prior to starting our tour. Things we wanted to see, anything we weren't interested in, etc. Once we started walking, he kept up a steady pace between pointing out interesting sites and storytelling about the history of Amsterdam. Never lingered too long and suggested a couple of breaks to give us a chance to rest our legs (and sample local beers! ). Bart knows his stuff and has "been around " so that his perspective is well informed. I would recommend this tour for a deeper dive into what makes Amsterdam such a unique city.
