We planned our short vacation around this tour, but unfortunately I can't say how it would have been because they cancelled it only 17 minutes before the tour! Given how they make a big deal about how they don't take latecomers, we were already there and waiting, and when no one showed up I called, and that's how I found out.
They said the one guide couldn't make it at the last minute, and another guide would have been late, so they cancelled. They should have honored their obligation even if the tour would have started late.
They did offer us another date and a 20% discount off another tour, but we weren't going to be in town at that point.
Bottom line: If you don't want to be stood up, go with another tour company!

We're very sorry that we had an unforeseen issue with the guide and had to cancel your tour at the last minute. As I mentioned on the phone, our guide wasn’t able to attend the tour due to the guide being locked out of her apartment with her sweet dog inside, and she was understandably worried about her dog, and we couldn’t find another guide quickly enough to operate your tour. We did reach out earlier in the morning, leaving a voicemail and sending an email in an attempt to contact you as soon as possible to let you know the tour had been cancelled, and we've issued you a full refund for your tickets plus a 20% discount on any of our tours to apologize for your experience. I understand that you were upset that we were unable to reschedule your tour for later in the day. If we could have done this to accommodate your group, we certainly would have. Since we use very small shops and restaurants, and on a busy Friday like that one, we were unable to push our reservations with these restaurants until later in the day to accommodate your group. Again we are very sorry for the experience you had, but we sincerely hope you experience any one of our tours worldwide.
