What is the operating time for the left luggage office

They offer 24-hour serivce.

Thank you.
When were you last there?

I don't think they work 24 hours as the station does not work 24 hours a day. See from the schedule, the station should stop working after 22:30 or so. Maybe it is possible to left the luggage there overnight, but you may not collect it during late night when the station closed.
