During the Sanfermines, the left-luggage office is in the College of St. Francisco Square, next to the Tourist Office. It provides uninterrupted service for 24 hours after July the 3^th at 8:00 a.m. until July the 16^th at 02:00 p.m. It has 1,200 spaces, all of then full at weekends. Americans and Australians are the most common users of this service, where more than 90% are international tourists. It is surprising to know how much weird things that have been deposited in previous years in the left-luggage office: hams, televisions… and even a helium balloon
