Just returned from Travelsphere's San Francisco to Vancouver.i stayed at Hotel Zephyr in San Francisco,very convenient for Fisherman's Wharf,but,it is undergoing renovation at the moment.The room was very comfortable,it even had a dart board and backgammon set,however the lobby is very small and only one lift working.
If you get the chance,the south end of the Golden Gate Bridge is worth visiting,great views,of the bridge,and it is possible to reach the walkway,on the bridge itself.There is a small information building,which includes a coffee shop.
