Cheap Places to Stay in Hong Kong

I am looking for suggestions on a hostel or guesthouse for a five day trip to Hong Kong this summer.  If anyone has any recommendations for a cheap, clean, and safe place to stay that has a decent location that would be great.  Thanks

The last time I visited Hong Kong I stayed at Yesinn hostel, at Causeway Bay. I think they have hostels in other locations too, but Causeway Bay was a great area to be based in. Very central, and lots of stuff nearby. The hostel is really close to bus tops and the MTR as well. I got the bus from the airport, the A11 I think! I stayed in the mixed dorm, which was cheapish but I thought it was pretty good for Hong Kong where a lot of the accommodation is super tiny and expensive. The staff were helpful and and it felt clean and very safe too.

well it depends on your defenition of clean and safe.. however cheap and good location I'd say Mirador mansions or Chungking Mansions in central Kowloon, many guesthouses in there, some with dorm beds some with single "rooms"
