I have business travel to San Fran (Mission St area). But I stay in Santa Clara for other reason. I have a rental car. What's the fast and cheap way to get into the city? I don't want to park there and pay $30/day. I guess what's the closet free parking for bus or BART into Mission St?
CalTrain <a href="http://www.caltrain.com/" rel="nofollow">http://www.caltrain.com/</a> ends at 4th and Townsend, then can walk or bus or cab to Mission. CalTrain meets BART at Milbrae (by SFO); BART runs under Market, which is parallel to Mission by one block. Google maps has a public transportation option.
