If you are looking for something different than the regular old corporate hotel room in a busy, crowded, overpriced central business district ... try the Seal Rock.
I was in SF on business recently and just did not want to stay downtown. I remembered the Seal Rock In and it was just perfect. The rooms were clean and comfortable ... although not at all fancy. The location is perfecrt. At the end of Geary Street off Golden Gate Park ... with an awsome view of the Pacific Ocean. I never heard any buses, but even if they would have been loud ... it would not have changed my opinion.. A big thumbs up!!!
