Rome, the Eternal City, also seems to suffer from eternal traffic congestion. But remember, there are lots of cheap and easy public transport options to help you get around the city.

Ride the bus or tram. Rome offers a network of more than 200 bus and tram routes, including 27 night bus routes.

Take a tour by public bus, rather than an expensive private coach tour. For an inexpensive tour of Rome's historical sites, take the 2-hour trip on the number 110 bus from Termini station at 2:30 pm (Monday through Saturday).

Get an integrated "Metrebus" ticket, which will allow you access to all the major modes of public transport within central Rome, with the exception of the airport link. You can get daily, weekly or season tickets.

Take the Metro (included on Metrebus tickets). This two-line metro system crisscrosses Rome, and runs from 5:30 am until 11:30 pm.

Walk! Rome is a large city, but in between bus or tram rides, see as much as you can on foot. Rome is famous for its piazzas and fountains. The best way to see these is as a pedestrian, but be careful. Traffic, especially motor scooters, can be crazy and pedestrians often have to fend for themselves.

Rent a bike or motor scooter - if you dare. Don't forget to take out the extra insurance.
