Drivers will make change for you, generally up to a 2,000-pta note. The metro is quick, frequent, and, at 145 ptas. Eleven metro lines crisscross the city, and there are system maps in every station. Note the end station of the line you need, and just follow the signs to the correct corridor. Exits are marked salida.
Crime is still rare on the system.

Parking is nightmarish, traffic extremely heavy almost all the time, and the city's drivers can be frightening. An exception may be August, when the streets are largely emptied by the mass exodus of Madrile os on vacation. Madrid has notoriously long morning and evening rush hours that can try any driver's patience.
