The Corinthia is an excellent choice and lives up to the reviews. We stayed in an executive king street view room. The bathroom and walk in rain shower are amazing. Street noise dies down at night and was not a problem. Location is superb with tube access right across the street. The Hungerford pedestrian bridge is right there as well for great views of the Eye and Big Ben/Parliament. If you haven't done so, walk out there at dawn or dusk on a day with at least a little sunshine for amazing views and photographs (take a tripod or rest your camera on something). The staff are very professional and accomodating, as one would expect with this kind of hotel. All lobby areas are very nice. The Corinthia will be our first choice of hotel for future trips to London, and we'll definitely stay there again. Expensive, but you get what you pay for.
The soft bed linens and fluffy pillows are perfect, although the bed itself was not as cushy as we hoped.More
