My fiance and I will be in Barcelona February 28 - March 6. I've never traveled internationally and know absolutely NOTHING about the area. We're both in our low 30s and hoping to make it somewhat of a budget trip. We're more night time people as opposed to early morning but aren't interested in the all night clubs and such. He loves his beer though! Any suggestions on where to stay? Where to eat? Must see attractions? Do's and Dont's? Tips and Tricks?
