Room status is clean room is VC, dirty room is VD, uncleaned living room is OD, cleaned living room is OC, and maintenance room is OOO. Please don't disturb DND and clean NNS. Usually, these letters are marked.

When staying in a hotel, you can call the front desk and ask them to arrange for your aunt to clean up. You can also inform the front desk directly. Or hang the hotel cleaning sign on the door handle.
