I am not fully satisfied with the tour. I was a customer of Viator for several tours in the past, however, this time I am quite disappointed. (1) In the catalog, it says "dig even deeper into the Old Town with your guide on a walking tour" - There was no walking tour at all. (2) The Guide was just saying her piece and no interaction with the tourists. The only thing I like is the mini-train tour & the 5 minute bus stop in front of United Nations to take a picture at least. I hope they will improve next time and provide value for money to customers. Thanks.
