I was locked inside the room as their door lock was malfunction after I put on the door knob latch at night.
Call housekeeping but they also could not open the knob. I had to wait till they called another guy for assistance. I think the hotel knew there was a problem as when I checked in late around 8pm, a guy came to the door to see if my room card worked or not. Anyway, this incident made me not too satisfied especially the morning I had an appointment to go to.
