If I could give this property six stars for service I would. Every possible accommodation was made and every single staff member was incredibly kind, pleasant, helpful and accommodating. The location is absolutely perfect, within walking distance to all the major attractions and virtually adjacent to Hyde Park. The breakfast was wonderful, and the room was large, comfortable and beautiful. The hotel is physically quite beautiful and it sits in the wealthiest neighborhood in London. The only possible negatives were the AC being slightly less cool than we would have liked (but probably more than adequate for most) and the shower curtain was hard to open and close. But when we mentioned the AC issue the hotel immediately brought us a fan that completely took care of the problem. I would/will stay there again without hesitation, and, again, would rate it six stars if I could for the impeccable service.
