What is the easy, faster, cheaper transportation / way going to Anne Black YWCA in Man Fuk Road, Hong Kong

1) What is the easy, faster, cheaper transportation / way going to Anne Black YWCA in Man Fuk Road, Kowloon from Hongkong International Airport?

2) What transportation (best choice) card should we buy / use if we are to tour around for 4 days?

3) From Anne Black YWCA in Man Fuk Road Kowloon, what are the best possible spots to visit within Kowloon Peninsula, TST and Hongkong Island? More of sight seeing, then some buying. Can you share some must see sites / places where we should go, and how to go there? Good for two days, from 7:00 AM - 11:00PM.

4) Would you be kind to give details on where to go first and where is next, so we can consume time going back and forth? Also where to ride and how much? And the last destination of each day, and way back to the hotel?

Thank you so much!
