We've stayed in quiet a lot Airbnb apartments in the recent years and we always try to choose outstanding and unique places and the Urban retreat is one of the best apartments we have ever stayed in. It has everything you need and is much better value than staying in most of the apartments in San Francisco. And Oakland definetly is worth checking out: great coffee stores (e.g. Blue Bottle), cool boutiques (Temescal Alley) and restaurants (Burma Superstar e.g).
In combination with this gem - it can't get any better!
