The transit in the city can be become truly chaotic during the week peek hours, so its advisable for the novices to use the bus or taxi. At night the reverse is true: use a car or get a cab or buses only when necessary (but if you check the timetable in STCP webpage you can reduce waiting times to minimum).
Although the daily pre-paid tickets are more economic (available in the STCP boots, post offices and some magazines kiosks), you can buy a ticket in the bus if needed (about euro 1,00).
More information about Buses available at www.stcp.pt (Portuguese and English).
