MOLLY ALDEN BARCELONA

My sister Alden and I are traveling to Barcelona, Spain in mid-April for 10 days and, having never been there before, would love any advice from those of you who are lucky enough to have been there before, or perhaps live there now!


The main thing we need to get sorted out is renting an apartment in the city.  Are there any especially awesome neighborhoods to where we should try to stay?  Any great apartment rental websites?


Any mind-blowing restaurants and bars?  We love food, drink and funky, off the beaten path, type places.


Flea markets and thrift/vintage stores?


Museums? 


Day trips, or overnights, we should seek out if we feel like venturing out of the city


Basically any sites that we shouldn't miss, or might not be listed in the common travel book. . . 


      THANK YOUUUUU!!!
