Taxi Cabs, Barcelona
Best way is subway but taxis are ok. Just get a younger taxi driver as they arent as rude as the old grouchy men. If you dont speak spanish definately get a young driver as the old men refuse to learn anything new while the youth learn english in school,
Well... nos so expensive as in Mallorca. There are lot of them, black and yellow cabs, comfortable and as quick as they can be in a city so crowded as Barcelona.
For me taxis are not the best choice for travelling around Barcelona. But if you wish to travel in good conditions, you're not in a hurry and don't mind the cost, here they are for you.
