We stayed here for 4 nights. The limousine bus from the airport took us directly to the hotel in around 80 minutes. The bus actually stops on the 5/F so there is no need to take any lifts to get to the lobby The hotel is actually next to all the major underground and train routes so is extremely convenient. For breakfast, don't go to the Japanese buffet which was bland, the western buffet is better but selection is very limited.
WIfi was super fast
