Shocking condition of a Singapore hotel that costs 70,000 KRW per night

Not only was it not cleaned, but it also reeks of stale cigarette smoke;;

They said they would change Wonji's room, so I checked the production crew's room first
(We booked 3 rooms for the crew as well)

The door wouldn't even open properly, so the staff barely managed to get it open;;;

At least this room had been cleaned, but

the moldy air conditioner was broken and the damp smell was insane

They said they can't provide a refund
If this were you
Would you just sleep there vs. consider the money lost and book another hotel?
+) Fortunately, the staff moved Wonji to a decent room at a different location
