Definitely Gaudi’s Park, La Sagrada Família, La Rambla (try paella that they cook in many restaurants along that street), the seafront and the beach…

But keep your wallet and your phone close to your body, preferably not in the backpack on your bag, but rather in one of your jeans front pockets. And put your hands on your pockets with valuables, whenever you find yourself in a crowded space. Barcelona is infamous for its street thieves. Even @allasyummyfood was unfortunately affected by a theft there a couple of months ago.

Having said that – don’t feel stressed, enjoy Barcelona, and have a great time!! We will follow your amazing trip via your blog. :)
