 The air conditioning I have stayed probably 5 times in the last 8 months first time I insisted on moving rooms now I don t bother asking as no room I have been in for the past 5 times has working aircon On top of that you cannot open the windows A tip for visitors is to shell out the extra for a Marina View with a balcony or any room with a balcony then at lest you will be able to open the doors 
 Its a cracking hotel all suites great value Been staying there for years when I am in town unlikely to stay anywhere else in London Perfect if you have a youngster who can sleep in the other room of the suite ask for a pull out bed You won t find these sized rooms for this price anywhere else in London
