I'm really glad to read what appears to be a consensus. The W London made it all the way to a leading position on the Starwood Hall of Shame.
What struck me is that W London was ranked by Conde Nast Traveller (UK edition) as number 13 of the Top UK Business Hotels with a score of 77.13/100 (Mandarin Oriental Hyde Park ranked at #1, scored 87.49).
I feel proud of being a FlyerTalk member where views tend to match reality by far more than the media "travel experts".
