This hotel is operated under the same chain as Royal Park Hotel The Shiodome. The hotel is conveniently connected to Haneda International Airport (but on the extreme end) hence there is no need to wait for a shuttle bus (unlike that in LAX).
The hotel is situated at the departure level but one must walk about 5 to 10 minutes from the subway station. Given the hotel layout, expect more walking as the hotel has a very long corridor (try getting a room nearer to elevator). The corridor however is wide enough to accommodate the luggage trolley, hence there is no worry about lugging your luggage.
