Hi, I am taking a cruise that starts from Barcelona and ends there. I will be flying into Barcelona on the same day as the cruise so won't have time to see anything but on my return I get into the city at 6am and I am thinking of taking a flight out of Barcelona at 5 pm so that would give me a few hours to see the city. That might not be enough but I can't take time off from work.
I only get the few hours on Sunday and want to make the most of it. Can someone recommend any safe place to store luggage? Also is everything closed on sundays (small ethnic shops)? I know that bigger malls and museums are open but I want to see local shops? I want to enjoy the local culture as much as possible in those few hours so any recommendations would be great.
