 It was unfortunate that there was a heatwave in London at the time The first room was in the roof i e Very hot no a c So asked to move to a room with A c This meant a move from a superior room to an executive room which meant more money but got a free upgrade in the end The only difference was the a c and size of bed The a c didn t work properly Got that fixed and all was well the second night The executive room was disappointing in that it was small and dark 
 The staff are friendly efficient and helpful
