The host is extremely helpful and friendly. Once you exit the building you will see the entrance for Jordan MTR. Its really convenient! Jordan MTR is between Mongkok and Tsim Sha Tsui which is awesome for travelling. Also, a short bus ride takes you to Kowloon MTR which you can check-in and drop off your baggage at the MTR (yes airport express stations allow you to do that!) before proceeding to take airport express to the international airport.
