We stayed two weeks ago at the Mandarin Oriental. First stay there as my usual place was the Bvlgari for years and before that the FSPL. We were pleasantly surprised with the size of the Mandarin room and the bathroom had a shower and a tub in a wet area which was unexpected (room description on the website is not very detailed). Service was excellent, even if breakfast was slightly disappointing. The Knightsbridge tube entrance right across is very convenient, the pool is nice and not crowded. Before opening of the Peninsula we would go back there with no hesitation!
