The other 2 reviews really said it well. This is a beautiful hotel with every comfort and luxuary. After walking all over london the luxuary feature is really appreciated. It is worth every penny and if you book direct with marriott.com you can get a pertty good price.
Our room was the largest I've stayed in in the UK, 2 doubble beds (not singles) and really nice long tub for soaking with nice quality products. The tube holborn tube station was right around the corner!
I did not eat at the hotel, TOO expensive, but there is a starbucks across the street (where I managed to pick up a free wifi signal) and a couple other brekfast places in the vacinity.
London hotels are fankly expensive, so why not spend just a bit extra for convience and luxuary and feel like you got something special for your money.
