We arrived at the Pisa airport, picked up our rental car and followed the signs to the Centro to find our hotel. It was near the tower so we figured we wouldn't have too much trouble finding it. We had a map to show where the hotel was but it didn't cover where we were driving at the time. The map didn't have street names which corresponded to the fact that some of the streets didn't have signs. We crossed the Arno, but soon we had apparently driven too far with no more Centro signs so we eventually turned around after a couple of false stabs and drove back with the intent of driving along the river to get closer to the town center. The configuration of one way streets required crossing the Arno again and then we got to a likely bridge and crossed only to find a pedestrian zone so we drove back on the other side, crossed the river, drove further south, crossed again for the 5th time and started back into town. In a bit we started seeing some hotel names including ours and followed them through many turns, going the wrong way on a one-way street for one bit (these signs were for pedestrians) and found the hotel actually finding a parking space almost in front of it - the hotel gave us a permit.
