To be honest, I don't remember exactly. I just searched

on Google, using key words: home for rent, and the name of your town, you'll find bunch of websites, whichever is free, just post your ads.

I just put myself on the renter's shoes, if I'm looking for a house to rent, what am I going to do? I'll goole first...

Maybe there is a better way to advertise, but I'm newbie as well, I just don't know...

Good luck.
