The Old Town is completely pedestrianised and easy to get around on foot. It's relatively simple to catch just about any bus as just about every one leads to the Old Town; however, it is still best to consult a map and timetable of bus arrivals/departures which will help you be sure that you are in fact catching the right bus.
