Comprehensive, though crowded
Word to the wise: There are night buses marked with N, but it is safer to take a taxi: public transport pickpockets are rife, especially on routes through the main sights.
Why you would take a bus when you can walk amongst the greatest sights in the world is a mystery, but if you find yourself in a hurry, or need to commute out of the city centre, the bus/tram network is well-developed, albeit crowded and slow due to congestion.
Bus and tram stops are called 'fermatas' and will have a yellow sign displaying the numbers of the buses that stop there, along with a list of all the stops on each route to help you figure out where you're going.
