Cost for living in Barcelona

<p>How much does it cost to study abroad for a semester in Barcelona?
I am studying abroad in Barcelona for the fall semester.
I will leave August 18th and visit my family in germany until the 29th. Then I will go over to Barcelona until the 17th.
I already paid for my program, and included are four weekend excursions and day trips. I also paid my flights already.
I just want to know how much it will cost for a few additional trips, and how much for me to live there. Just a ball park range, any opinion or past or present experiences will help.
I was thinking 5 grand would be good.</p>

<p>Thank you lprizzle. My S is just entering college but is already talking about Barcelona. Your links will help him get more information.</p>

<p>Thanks thats a lot of information but do you have more examples of actual numbers. It doesn’t have to be exact just an idea?</p>
