The room was fine, just ordinary clean hotel room, but receptionists were unfriendly and the housekeeper broke into my room even I had hung the 'Please do not interrupt'sign on the door.The housekeeper was a man and I was sleeping half naked. I asked who he was but he didn't answer and just ran away. I was terrified but they were not sorry about what happended on the phone. So I talked to them face to face and the receptionist treated me as a tiresome guest and offered me a 'a glass of champagne voucher' as a compensation.
