For those still looking for a place to stay, I live in the Bay Area and would recommend staying in Emeryville or Berkeley (not Oakland, as it is not safe). Hotel Shattuck Plaza in downtown Berkeley is pretty nice, and is right next to the BART and buses. Honestly, though, I would just rent a car and drive to Samuel Merritt, rather than take the bus to that area. In Berkeley there is also Doubletree Hotel right on the Bay in the very quiet marina area. There are some cheaper ones, too, on University Ave, like Holiday Inn Express, that are not bad. There are also locally owned hotels like Bancroft Hotel and Rose Garden Inn, both near UC Berkeley, that look nice. Hope that helps!
