-Think of reserving your tickets for the cultural sites (Sagrada Familia, Casa Battlò, Park Guëll etc.) on-line, to avoid waiting several hours in the line. And try to obtain reductions in tourism office,  because tickets are very dear (approximately 20€ for Casa Battlò for exemple).

-Take a card of 10 itineraries (subway, bus) - Approximately 10 €- rather than to pay tickets to the unit - Approximately 2 €-.

-Take away of the city center to accommodate you.

-Don't fall into the trap of the frozen paella, a real home-made paella is generally served for 2, in a big dish of cast iron!
