Found it!

Having just spent a gorgeous weekend in springy, sunny Vankie, I was thrilled to visit Craig's List to discover my dream roomie:
Free for young, free-spirited girl
I'm 36 single male, chauvinistic, a little perverted for young thin women, but quite harmless and very respectful. I just like having young hot girls around as..well, decoration. You get your own room(there is a lock on the door) some cooking required. Its a win/win situation for both of us...I eat better, have pleasant eye candy around, you live cheap and you'll love my cat.

And here I was thinking that San Francisco was all liberated and everything.
