The hotel is located within walking distance of the Tokyo international forum/ exhibition center and the Imperial Palace, Ginza shopping area and theatres.
This central location can definitely explain the high price. The hotel is located next to Tokyo station, it may be a bit noisy but very comfortable for traveling out side of Tokyo. It is also 1 minute walk from Otemachi station that gives an easy access to all districts of Tokyo.
In the hotel you will find some restaurants and cafes.
