Ask HN: Looking for an apartment in San Fran. Can anyone help?

I live in Australia but, will be relocating to San Fran in two weeks. I have been trying to find an apartment online. Unfortunately, there are way too many scams out there and it is very hard trying to filter down between real & fake postings.

I have tried looking through many different listing sites (including the usuals such as cl etc..).

I don't know anybody in San Fran so, need to find and lock in something before I get there.

I am looking to be around SOMA, Rincon Hill, Downtown etc...

Can anybody recommend any real estate agents, apartments or legit websites that I can use?

Thanks,
