 Nothing in regards the hotel although now I know there are no front facing deluxe rooms I would reserve a different room type next time Its also a bit expensive in our view but at least you know that up front 
 The location the fact it is not a huge hotel so you are treated more as a person rather than a number the d cor in the rooms and the fact each one is different the type of building its a relaxing place to stay amongst the bustle of London
