My friend said it wasn't necessary to clean the room, but the housekeeping should be smart enough to clear the rubbish bins & wash the cups at least. So I have to ask the housekeeping to come in to throw those rubbish. At the same time, I can't wait anymore for the engineering to fix the drainage although I have informed the reception for 2 days about this issue already, finally the housekeeping helped me when he came in to clear the rubbish bins for us.
