The hotel is very well located, near Embankment tube station, 5-10 minutes walk: London Eye, Trafalgar Square, Big Ben, but in different directions.
About the room I can tell you it was large, about 50 square meters, there are different types of rooms depending on the number of people and equipment.

Room was overlooking the hotel's courtyard, very quiet, free from outside noise.

Mention that the hotel is located in an intersection and has 2 sides to the main road, both noisy.

I stayed at the Corinthia last week on a business trip, but absolutely plan on returning for pleasure next time I vacation in Europe. The hotel is beautiful, the service exemplary, the location is excellent (20 minute walk from most spots of note in the city) and the rooms are both plush and comfortable. The other reviews speak to the heated marble floors, the beautiful artwork, etc., so I won't reiterate all of those details but will instead confirm their accuracy. One aspect not written about in great detail is the spa/pool, which is absurdly nice (4 floors, whirlpools, Grade A sauna and steamroom). The breakfast was tasty, albeit rather expensive.

The only "negative" I can raise is the bed. While it was billed as a king-size bed, it proved to actually be two mattresses pulled together (with king bedding over the top). I experienced this same set-up in a number of very nice hotels in Italy, so perhaps it is the standard in parts of the EU, but coming from the US, the crack in the middle was not all that enjoyable...

This hotel is perfect in everyway. The service from the time you arrive is second to none. The staff know how to make you feel very welcome and tend to your every need.. We had booked a delux courtroom room which was large and spacious. The bathroom was superb as it had a large bath and a separate large shower. Our walk-in closet was perfect for storing luggage. We only had breakfast in the hotel once which was delicious. A wide variety of food to choose from.
I would highly recommend this hotel for 5 star service. accommodation and location.

The Corinthia is sublime. Every aspect of my stay was excellent; service, accommodations, spa...everything! This was my second stay at the Corinthia and I will be back. The room was spacious, well appointed and the bathroom was amazing. For both stays my room was large, with a walk-in closet and a foyer. Even the art on the walls feels personal not the typical anonymous hotel room decor. The service was outstanding from beginning to end. The spa is not to be missed. I was pampered and left feeling like a new person. The Corinthia pays attention to the details of its accommodations, spa offerings and ultimately its customers. I will summarize my review of the Corinthia with two words - quality and service.
