First time in Copenhagen. Me and my wife spent the weekend and looked up free walking tours in TripAdvisor and these guys showed up. We've done a couple of these through out Europe and Canada and they haven't disappointed us. We had Martin as our guide and he was very funny and very knowledgable. He made the tour even better by telling funny stories that happened to him by the tour stops...made the tour very funny. During the break, he recommended trying the bacon wrapped hot dogs, I mean, bacon wrapped hot dogs...amazing! I will definitely recommend this tour to all my friends.
Also, remember to tip these guys well. They really deserve it!
