B1 next to toilets
Changing table, seat. Changing table is parallel to wall and perpendicular to where you are standing, thus difficult to change diapers. one cubicle only. Electrical point is not available.
Changing room is locked and the key is available at the information counter on the same floor. You have to sign out in a book, and the person will open the room for you. It is a bit troublesome but I guess it is a good thing as the room will not be misused for other purposes.
