Hit all the main points of interest, but only drove by them. The guide was kind enough to speak in all the languages of the people on the trip but didn't give very many descriptions. If you just want to sit on a bus and watch the sites go by, this trip is fine. Otherwise, I suggest walking around the city yourself- it is easy to see many things just wandering by foot.
Guide was very interesting and gave nice details about what we were looking at. Would have been nice to have a little more time in each place. Don't recommend going to the restaurant he recommends you. It was too expensive, and the food wasn't very good. Would recommend the tour though.
