Does A21 Hong Kong airport express bus goes to Ovolo, 256 Tung Chau Street?

Bus A21 can not take you directly from the airport to that place. You can get off the bus A21 at Fat Tseung Street West, Sham Mong Road, then transfer to bus 702 and get off at Nam Cheong Estate, Yen Chow Street West. Then you could walk about several minutes to your destination.
