I posted this in my London journal and thought it might help those of you headed to Barcelona as well.
The best deal for Internet access is at a place called easyEverything. The price depends on the hour that you are using it but generally you get 45 minutes for about $1.50.
It is extremely cheap for Europe, where Internet access tends to be a bit of a highway robbery. We saw one place in Switzerland that wanted the equivalent of $20 an hour!
This cafe had 415 computers and is located by the main strip of La Rambla. The address is:
La Rambla 31,08002, Barcelona
You don't have to use your whole 45 minutes at once if you don't want to. Just bring back the ticket and punch in the password on it to continue. They have coffee and snacks as well.
Just look for the bright orange awning-you can't miss it!
