Gurus English was pretty poor. Talked very fast and used lots of slang too hide this and was repeatedly being asked to confirm what he had said by myself and the rest of the group. It seemed that more than half the information provided was to tell us which buildings were being repaired and what they were being used for currently (both of which were clearly obvious). Passed another tour at one stage where the tour guide had great English and genuinely wished we could have left on the spot to join it. Have done 15+ tours with guruwalk and have never thought which tour was the worst (only tried to rank them by best), this was certainly the worst in terms of providing any actual information. Tour was advertised as 2.5 hours but taking into account how late the guide was and when we finished it was less than 1.5 hours. Guide very much seemed to want to walk around talk about what he knew and then get the money and leave.
