Never stay at Chung King Mansion...as too many foreigners get robbed there and also getting ripped off for a cheap hotel, but in return they stay at places that are inhabitable or below standard of living and paying premium prices with no refunds. Just stay avoid renting from there!!!
How many minutes from the airport going to Canada hotel? I'm going to HK and will be staying in that hotel on March 2016. I hope i'll not get lost. Btw, did you used octopus card for the bus?
