6. The Opal has a good location with access to convenient transit connections (bus lines on Van Ness to The Marina and Fisherman's Wharf, a souless tourist trap, and Geary to downtown or out to Richmond, as well as a cable car down California - pick up day or multiday transit pass at the Holiday Inn up the street at Pine) The hotel itself is reasoble for SF, but the carpets are about 10 years overdue for replacement, and the breakfast was - well there is a diner attached that might be a better option.
