David's place provides you with a comfortable large room on the second floor. He's a great host; attentive to your needs, very generous and interested in making sure you get the most from your visit without ever being overbearing.
If you're thinking Oakland is a bit far from SF as that's where you'll be most if the time, the train will get you over there pretty quickly. David also introduced me to the carpool just across the road from the house which will get you in there each morning for free. The personal tour of SF on a drive he took me on the day I arrived was very memorable despite my jet lag, introducing me to interesting sites at other places in the Bay Area I was previously unaware of. I enjoyed my stay and hope you do too.
