I agree, it was nice going by train. We took the Saturday 10am train and it was packed, standing room only. Its a good walk to the old city but I didnt' mind we really enjoyed it and the locals got a laugh out of us trying to ask directions. At the train station there is a car rental booth and they gave us a map to the Tourist information, which was really helpfull when asking for directions.
