The Left luggage room is a designated area in a hotel where guests can store their luggage before check-in or after check-out, for convenience.
- Lost and found room is typically where lost items are kept, not specifically luggage.
- Bell desk is where guests can inquire about luggage assistance, but it is not the storage area.
- Back area is a generic term and does not specifically refer to luggage storage.
Thus, the correct place to store left luggage is the Left luggage room.
