What is available to Storage of luggage at Barcelona?
Your accommodation, a couple of the train stations and the bus stations probably. Where do you want the storage? For how long? When will you want to collect it?
Jo Ann, there are lockers in the Barcelona Sants train station. Here is a link to a picture I took as I walked past them. There is a large sign that says Consigna in Spanish and Left Luggage in English but I suspect they refer to the lockers. There may be a staffed facility but I didn't see it. I did see the lockers. http://gyazo.com/28131b73c75d5b41bf89bd9453c9d3db
