Universitat de Barcelona (UB)

I wish I had made more of an effort to meet spanish people because I really did not have a spanish experience, but rather I had an American experience in Spain. Also, keep in mind that Barcelona is a very big and at times impersonal city... people are not as friendly and inviting as they may be in the south. If you are going to make spanish friends, it is up to you. Finally, Barcelona is not stereotypical Spain... it is Catalunya, which means no flamenco, no bullfights, etc.

If you take classes in the Univerosty, then I strongly recommend it because it is beautiful and you will learn a lot. But remember that it is very big so it does not have any type of campus feel.
