We had two consecutive days with Chris and he was able to show us the vast differences between different parts of the city. We rode the metro at the stop that goes through the building and explained the differences between the two types of metros. He made sure we had the true experience and saw it from the local side of the city. It was nice to have him take control of didi and involve us in the process, so we were familiar with how to use it. If you are looking for a great guy to show you the true local experience but can also direct you to the typical tourist spots, Chris is your guy.
