I am going to be in Hong Kong for four days in a couple of weeks time and I am looking for some accommodation. I have a room booked in Chung King Mansions but everything I've heard about it so far has been negative. Do you know of anywhere else that is in a similar price bracket but not in the mansions.
I stayed at Dragon Hostel last year and it was pretty good as far as hostels go. It's in a really central location in Mong Kok and the manager is a really friendly guy.
I haven't heard good things about Chung King mansions either; similarly Mirador mansions which are nearby.
If you haven't already done it, try the 'accommodation' option on the left panel. Choose 'Hong Kong' as your country, click on budget accom. and see what is out there. I found several under $20/nite. Write down the name and then go to 'tripadvisor'. Read the reviews of others that have stayed there and reported their experience. Good Luck with your planning.
