Post in Sant Cugat del Vallès, Catalonia, Spain

Hi! We are an Argentinian couple arriving in Barcelona the 2nd of August and we are planning a 2 or 3 months trip around Spain and Italy. We would like to travel with 1 backpack each, so we are looking for a place to leave 2 suitcases and 2 backpacks while we are traveling. If anyone can help us we would appreciate it 😊😊 thanks !!
