We weren't sure our trip was going to happen. Our guide didn't show up and another one was promised in 30 minutes. While we were waiting the biker trip got cancelled that day because the guide didn't show up. We were getting the picture that the guides weren't highly reliable. But when we did get underway, it was a great overview of the city and the substitute guide was knowledgeable and friendly. We saw a lot of the main highlights of the city that we went back to the next day. great price and value!
