Nice room, nice gym, club lounge so-so. AC terrible. When I arrived 19pm, the AC was in 17°C in cooling mode and it was freezing. I changed 21°C. Was away until 23pm, and when I got back it was at least 26-27°C in the room so I turned it down to 19°C, then 17°, then 5°(!). Nothing happened. The AC was in cooling mode but was heating so finally I turned it off and ended sleeping with windows open (with my asthma in Beijing!). When the sun came up the room was unbearable, a sauna. I did not report the problem because of the lateness.
