I went there with a couple of friends this past March and had a good time. Like others have said, you have to be aware of pickpockets especially on the Metro and on La Rambla (pedestrian mall). Some people warned me that they will try to distract you while little kids do the pickpocketing. We didn't have any trouble, though it might be a different case if you are wandering around by yourself.

I would highly reccomend checking out the Gothic Quarter which is the old part of the city. The Picasso museum is there and so is the Barcelona city history museum where you can see some old Roman ruins under part of the old city. It is a bit of a hike, but the Castle de Montjuic is a fort on a hill at the south eastern part of the city offering some great views. Gaudi's buildings are throughout the city and can be pricey to tour if you want to see them. I think the church was best viewed at night.
