Cost : a single ticket is €1.50. The ticket is valid for 100 consecutive minutes on buses/trams and is valid for 1 trip on the metro/underground.
Bus/Tram : single ticket is valid for 100 minutes (consecutively) from the time of validation. You can use the ticket for as many buses and trams as you like in the 100 minute time frame, but the ticket is only valid for one use on the metro/underground. When you get onto the bus/tram, look for the small yellow/black boxes and insert your ticket. The ticket will come back stamped with an expiry date/time.
Metro : single ticket is valid for 1 trip on the metro/underground (this includes transfers). If you plan to use the metro/underground twice, even within the 100 minute validity period, you will still need to buy two tickets. Be aware not to exit the turnstiles when switching/transfering metro lines, you will be required to purchase another ticket.
Where to buy : Metro stations, newspaper stands, tobacco shops and cafes (those that sell tobacco). Tickets cannot be purchased on the bus, so make sure to buy tickets in advance and keep a few extra on hand if you plan to use the bus often. The bus driver will not check your ticket and you are expected to validate your ticket when you get on the bus. While this is mainly an honor system, there are officials that will get on the bus and check that your ticket is valid. Any person without a valid ticket can expect to be kicked off the bus and given a fine of €50 – €100.
