I've heard that we can leave our baggage in lockers for few hours in SBB central stations, but I'm a bit worried about the safety. Is it easy for thieves to reach the site at which lockers are located and then open them to steal the luggage? It is a lot safer if lockers are in a locked room. Or is it possible and better to leave our luggage in left-luggage office where someone is responsible for keeping luggage safe (I'm not sure whether the function of the office is like this@@)? Really hope for your answer and your effort will be much appreciated!!
