I used http://www.padmapper.com/ when finding an apartment a few months ago. It's basically a Craigslist/Apartments.com/etc aggregator that puts each listing at its approximate location. Super useful, especially if you are moving to an unfamiliar city.

Aren't there lots of good alternatives to Craigslist now?

At least here in the UK, we have the following which are good:

http://nestoria.com

http://rightmove.com

http://findaproperty.com

http://www.globrix.com

try http://sfbay.cribq.com/

or the mobile version http://itunes.apple.com/app/craigslist-housing-maps-cribq/id...
