Spent four sleepless nights in this hotel, in four different rooms. There is a light that is motion activated in each room that turns on, even with the sensor blocked and no movement whatsoever in the room, spontaneously. And it made a habit of doing this while I was sleeping, every 1 to 2 hours, waking me up. Hotel staff said they were aware of the problem and apologised for the "inconvenience" but would not refund me so that I could move to another hotel. Inconvenience is an understatement. I was delirious by the end of the trip from lack of sleep, am now ill and missed a big chunk of my business events as a result.
