Replying to Study abroad spain

Hey guys i am thinking of studying abroad in Spain this next fall. I was wondering if you think Barcelona would be a cool place to go. I want to go to a place where i do not know the culture or language, I plan on traveling a lot when I am out there. I heard flying is pretty cheap or getting a euro pass. I just want everyones opinion on this or other countries in Europe that you think would be a good place to study abroad. thanks! any info is appreciated
