1 month rental in Koh Rong

Have you checked on Airbnb? I see some that are a bit more. Is the $300 a firm thing?  I also see some on booking.com for higher and lower if you want a tent :-).  You may want to check on agoda too. Those are usually my three places. I open a web browser tab with each showing the offerings and compare them side by side.

Please check out this beach, it is possible to rent a tent at the beach (with a bathroom building) for only $10 a night based on 29 nights.

I guess it's the only way to stay within your budget.

I have been that island once, and spent $10 for one night living, there have a lot lodges on the beach, just going there and you will find what you want, however one month living there alone for woman is not safe and too boring.

#4 who are you to judge what's boring?
I've always thought just turning up is best.  However, don't forget the Khmer new year is in April.   Good hunting
