Step one - cancel your reservation at the Wharf Just my opinion, but in the game of "which one does not belong" it's the wharf location; it's just not in the same league with the others.

Between public transportation and walking (SF is not a large city, just a lot of hills!) you can get around very nicely without a car. I'm sure many people will jump in with thoughts on the other locations - I've only stayed at the Fourth St. location and was treated very well.

Have fun,
