Admiral, et.al, glad you found and liked the Colada Expres chain of laundromats in Santiago de Compostela.
As Puna mentions above, this is a chain of laundromats spreading far and wide and even I've used them for big items like comforters or heavy blankets. The outfit has big washers and big dryers and is pretty affordable, too. They're mostly in the big cities, however.
for Barcelona information, Transportation, Lodging, & much MUCH more!
