Rome is unlike many modern European cities where the trains or subways are designed to directly reach important tourist attractions. This city has so many ancient architectural sites above and below ground level that the rail transportation system was built around these important sites, making sure that no heritage was damaged. As such, it is highly recommended that one should pack along a pair of good sport shoes. Furthermore if you are not travelling with a tour group, it is advisable to buy tickets and take a round trip with the Hop On Hop Off bus so that you will have a good idea and perspective of the city of Rome.
