UB Sports bring back such fond memories of playing football in grad school! The complex at the University of Barcelona features a large indoor pool, gym and fitness, racquetball, tennis courts, football fields /pitches of all sizes(small ones for 5×5, also half– and full-sized fields, some grass, some turf. The booking process can be a bit challenging and the facilities are wayyyy at the very edge of Barcelona, but man is it nice to kick a ball around then head back downtown for a beer.
