The tour was very informative and fun, our guide had a lot of knowledge and keep things interesting. Overall a great tour. The only caveat is that the tour had way too many persons on the group (we counted a least 25+) Even wt a sound speaker it was difficult to feel engaged since there was so many of us it was difficult to get close and listen to and watch pictures on an iPad, let alone trying to cross street and waiting for the whole group to regroup safely. Each tour should be no more than 15 persons for an engaging/safe experience.
