Has anyone had any luck using a rental realtor? Have any recommendations?

I currently live and work in the south bay but want to move into the city sometime in early April. I've been using craigslist and padmapper, but I need another resource to help look for places.

If it makes a difference, I'm mainly looking for a studio/1bd in noe vally/mission area. Any realtor suggestions would be really appreciated.

Thanks!
