Hello. Can I ride Bus A21 from Novotel Citigate going to Mirador Mansion in nathan road? Thanks

Well, It seems that bus A21 does not run from Novotel Citigate going to Mirador Mansion. The best way for you is to walk to Tung Chung Station to take MTR Tung Chung line. Then transfer to West Rail Line at Nam Cheong and get off at MTR East Tsim Sha Tsui Station - N5. Walk about several minutes, you will get there.
