A Stylewalker-recommendation: The best internet café (and of the cheapest) in central Barcelona is “Electric“. Situated right next to the cathedral, on Missa Ferrer it has a very modern and industrial style.
Since they opened only two weeks ago, it is still quite minimally decorated and right now the two owners (cool guys from Berlin!) are talking to artists to decorate the place.

Members pay 1,20€ an hour and get coffee or tee for free!
