How do i get from Central station using AE card to Ovolo Hotel Central Arbuthnot Road?

Well, there is no direct free shuttle bus. Notably, the Airport Express Card cannot be used on MTR. You need to recharge some money on it. Then it can be used as the Standard Octopus Card. From Central Station, just walk southwest around 400 yards to find your hotel. You don't need to take the public transportation.
