1. Eat at Ciudad Condal for amazing tapas! 2. Visit Parc de la Ciutadella 3. Go to the local market La Rambla and get 1 euro smoothies :) 4. Basically everyone who goes to Barcelona will visit the La Sagrada Familia (this is my other favorite church in Europe). Make sure you book your tour online beforehand because it can sell out. 5. Party at Club Opium and make sure you put yourself on the guest list first! Expect to leave around 5 in the morning...
