We have quite a bad experience as we found that the staff’s key inserted on the room door keyhole without any supervision when we backed to the room at late night (12:00am). It’s meant that our room was opened and unlocked nearly a day (The housekeeping time is start from 10am). They did not provide us a satisfaction reply or investigation report to explain why it happened. We paid quite a lot for a room as it was Sat Night. This should not be happened at any circumstances.
