Here I come

It's finally decided, Christian and me are going to Barcelona this fall. I'm really looking forward to it, I love Spain! I haven't actually been to Barcelona, only a lot of other places in Spain, so I'm really excited to finally go there. We've talked about going somwhere warmer this fall since this summer, but haven't quite decided where, until now! Have some of you ever been to Barcelona? Please tell me about where to go, I'm all ears!
