There is a lot you can do in 3 Days. Suggest to include Gaudis Sagrada Familia, get there early around 9 Am as there will be less of a queue. It's a magnificent structure. Plenty of wonderful Tapas bars on Los Ramblas. If you can fit in a day trip by train to Mons Serrat it is a monastery situated on a mountain which you can access by cable car. We had a great lunch in the cafeteria there. The markets just off of Las Ramblas are well worth a look. Double decker bus tour will show you the highlights of the city. Have fun! about 5 years ago
If it´s possible for you to stay longer than 3 days, I would, especially if you´re planning on doing Montserrat because that is a day trip in itself. Barcelona has so much to offer, and besides seeing the tourist sites, you´ll probably just want a day without plans to simply explore the city. I would also suggest the funicular at Montjuic, which offers some amazing views and is quite easily accessed through the center of the city. Hopefully this gives you some insight!
