Hong Kong is a fantastic place to go on vacation and staying there for a month will mean you'll have time to really experience the lifestyle for yourself. There are several different kinds of accomodation available but the cheapest option would have be a hostel. If this is something you would consider there are several available. The cheapest one i know of is Hong Kong Downtown Backpackers. They offer a bed for 7.65 dollars a night. That would be a room which sleeps 25 people with a shared bathroom. However they do offer smaller rooms for example a room which only sleeps 3 people, or a room on your own. To have a room alone the price would rise to $13.64 and again this would mean you'd be sharing a bathroom. To have a bathroom of your own the price would go up again to $18.89. This hostel and many more like it, is in the Kowloon area. It is very popular with tourists and there are lots of
things to do. This is where the action is, hundreds of bars and clubs, restaurants and hotels line the streets, remaining active well into the early hours of the morning. I would suggest this would be the prefect area if living within a budget. For a small price you could spend the day enjoying everything Kowloon as to offer. If you were looking for a quieter area you could try looking at Hong Kong Island. This is where you would find the highest point in Hong Kong
victoria-peak it is also where you will find some stunning beaches if your willing to travel a little further. There is information on transportation avaible here

There really are a huge number of hostels and hotels filling Hong Kong. I hope this helps, but if you would like to narrow it down to a more specific area i would be happy to recommend more hostels, or even a guest house if thats what you would prefer.
This map might give you a better idea of where these areas are.
