Pausanias

Very few London hotels have great views and those that do, very few rooms or suites have that benefit. Mostly the terrain is flat, the roads are too narrow and the buildings are too uniformly tall (about six floors) to afford nice views. I'm going to name drop here, but I do remember booking the great movie director George Cukor into the 'Katharine Hepburn Suite' at the Connaught which had a tiny terrace from which you could just about make out Big Ben. (George had a much better view from his house on Cordell Drive in LA.)

Some rooms at the Savoy have river views towards the RFH. The Marriott County Hall has stunning views towards the Palace of Westminster (currently under renovation wraps). The Shangri-Shard . . . of course. The Hilton Park Lane looks down on Buckingham Palace. The Lanesborough looks out on a roundabout. And a few facing Hyde Park such as the Dorchester and the MO. But nothing to get excited about from any of them. So not worth shelling out for.
