Besides the obvious but not trivial immersion on the arty side of the city, don't forget to climb up the magical Montjuïc, get to know the city's history, follow your path to heaven visiting the several holy buildings, go for a run in this sporty metropolis, take a dip in the Mediterranean and tan under the warm sun along the Barceloneta... think that these are only a few of the many things that a smart traveler like you can enjoy!!!.
