Having just spent a long weekend in Barcelona, with only a few hours to cram the whole city in we were constantly using the metro (once we'd figured it out that is!)
Advice on metro:
My most importance advice for the metro is buy a T10 Card! Absolute lifesaver - only needed two for 4 days of gallivanting.
T10 Card in short is a train ticket which can be used 10 times and can be purchased at any metro station entrance.
All the machines have an english option which makes it super easy to use plus there are always attendants nearby to help a sister out especially in the bigger stations!
One ticket can be used by two people which is sooo convenient. Each of you pass it through the machine and it'll stamp the ticket with a number on the back. This is also useful when trying to figure out how many more journeys you have left on it!
