BUNK + Apartment List =AWESOMESAUCE
It's tough finding a roommate in San Francisco, we hear ya. That's why we started Bunk-- to help people out from behind their computer screens, meet people (real people), and take positive steps towards finding an apartment.
Craigslist sucks so we came out with an app specifically for San Franciscans to meet each other and potentially sign their own lease. It's waaay easier than bullying each other for rooms here and there and it's free/easy to get started.
Anyway-- I'll get off my soapbox and let you get back to it. Check out the app, swing by Apartment List to say hello, and best of luck with your search!
