Watch where you park. It looked as though you could not enter the city walls without a pass and spaces are few and hard to find. Outside the walls there is literally no place to park, like a public lot. We started driving up the hill and kept wandering until about 8 blocks later on a steep incline, we found a place to parallel park on the street. I imagine in the summer time with a lot of tourists and buses, this is a mad house and quite congested. You need to watch the sweat form a bus driver trying to manuveur around the intersection at the city walls. The turns are really tight and it takes about three back and forth for them to just get by the cluster of cars and people outside
