"For a 3-day stopover in Japan, this was an ideal location. After exiting customs at Haneda Terminal 3, it is about a 10 minute indoor walk to the hotel. Also in the vicinity of this indoor area are turnstiles to the trains, as well as access to shuttle buses to various places.
We arrived late so the Lawsons near the hotel entrance was perfect to grab food and snacks to take back to the room. If you arrive between 11 am and 8 pm, there are many restaurant choices indoors by the hotel as well.
There is a self-service, automated laundry room at the same floor as the lobby. You could drop off and leave your clothes there, and monitor the progress on your hotel room tv.
One of the days during our stay was rainy, and the hotel had umbrellas you could borrow for free at the Cloak section. It was very useful and convenient.
The staff was also very helpful and pleasant. We had a great stay here.
Just for additional information, we flew into Terminal 3 at Haneda, but departed from Terminal 2 when our stay ended. To get to T2, you have to walk with your luggage (carts are available at the lobby) back towards T3, take an elevator down, and walk to the appropriate bay for the shuttle bus to T2. Having 2 heavy suitcases, a carry-on and a personal item was difficult, especially because the shuttle bus did not have an undercarriage compartment to load them into. You take them inside the bus with you. Space could be an issue as well.
