Hi deezee,
The first thing I would suggest is to take more time. I don’t believe you can make a good choice in a day and I would rather sleep on a sofa or on blankets on the floor for a few days than make such an important choice in a single day. While you may be uncomfortable for a few days … I think that’s probably better than being uncomfortable for a much longer time.
The next thing I would suggest is to read post #1 in this thread which is a step by step process that can lead to the best possible choice for your needs and preferences.
The best options I know of in the San Francisco area are in post #2 here.
You have some great options in your area but the odds are overwhelming that a single day is not enough time to do some initial reading, make the initial phone calls, and do the testing that is necessary to make your best choice.
