The stay was ok, however as reported by many other guests, the air conditioning is completely ineffective. The room was 25.5 degrees. Having set the controller to 19 degrees (the lowest it would go), I hoped to hear the ventilation come on and the room to start to cool. However, it was questionable whether there was actually any cold air coming through the vent as I could not really feel or hear anything. When I awoke in the morning, the temperature on the panel was 24.5 degrees even though the temperature was still set to cool to 19. Since it is not possible to open windows in the room, this meant for a very stuffy and interrupted nights sleep. With many other guests reporting the same issue, it sounds like this hotel needs to invest in upgrading the air conditioning system.
