The area around 3rd and 20th is actually pretty well connected transit-wise (near 22nd st caltrain, the T line, and three or four bus lines), is a 30 minute walk from soma, and is still pretty cheap. And although the real estate prices are going up (along with the rest of the city) there's still a lot of underutilized land to expand into that should act as a buffer on rent prices. If I were looking for a place to start an office I would look there first.
I lived a block from 3rd and 20th. It's a reasonable place to live, I liked it, and it is indeed next to Caltrain, the T, and the 22 and 48 buses.
But there isn't a lot right there, it always takes at least fifteen minutes go get where the action is (i.e. the Mission). I recommend it for anyone who commutes to Stanford, Palo Alto, Mountain View, etc. but wants to live in the city... but if I didn't have my commute I probably would have lived in the Mission/Castro/Hayes Valley/etc.
