Hi,

we will be arriving in Hong Kong by plane around 5:00 p.m. in April. What is the best way to get to Best Hotel(Hostel) in Kowloon, Jotun 322-326A Nathan Road, Kowloon Park Building 4 Building .

On the map this hotel is located on Austin Road, east of Nathan Rd...but the address is Nathan Road ---what is then the correct address?

please help
