When we were in Old City, hubby and I did our own walk tour. There were tourists that tour the area in groups with a tourist guide. Since we do not want to spend for that, we manage our own tour with a map of the area. Look at the narrow street and the old building, you will really see the charm of this place.Here is another plaque that says about a historic house here in 1798.
There are so many things to do here aside from a walk tour. You can also rent a Segway if you do not want to walk. I would probably do that on my next visit. Segway is fun!
