For me, this was a first time stay and a departure from my regular London traditional "home from home" hotel, The Dorchester.
In many respects there is a great deal of similarity, room style, furniture, views of Hyde Park etc they even serve the same room service butter with breakfast !!
But I can't help feeling they are trying a bit harder as the staff attitude was exemplary, at all levels.
Reminded me a lot of the two bastions for this the Peninsula's Beverly Hills and Hong Kong.
It does have the advantage of being on top of the Knightsbridge shops aka Harrod's etc and many restaurants some of which are top class, not least Mr Blumenthal no less, in house...
I would most certainly recommend it for those looking for a top traditional hotel in London and not wanting to be in Mayfair...
