I like using the soufun.com website to search for rental listings. Here is a listing of 2bdrm units in JiuYanQiao between 2000 and 3000 RMB. What I do is use the Firefox browser with the Perapera-kun plugin which translates the Chinese in tooltips as you mouse-over characters. Or you could use the Google Chrome browser which does automatic translation of the entire page.

Also check out their map feature which I’ve found super helpful finding units in the exact block or complex you’re interested in.
When you find a unit with pictures that you like, I’d ask a Chinese speaking friend to help you call the agent’s phone number listed. Make sure to ask if the specific unit is still available and to confirm that any details described on the ad is actually true. Sometimes they will list that there is an elevator but in actuality its a walk-up. I think they just sometimes copy details from another agents ad without making sure its accurate. Also ask if they took the pictures themselves and/or have been to the unit. When scheduling a time to see a unit, ask if they have the keys to enter the unit or whether they have to still get it from the landlord otherwise you might arrive at their office and they will say they don’t have the key yet and do you want to see some other units while you wait for the landlord to come in a couple hours.
