You might want to briefly look over a map of the SF Bay Area - it might help you get your bearings.

SFO is just south of the city of San Francisco.  Sometimes it is considered San Francisco and sometimes it is called the 'San Francisco peninsula region' and sometimes just plain ol' SFO and some even call it the 'airport area'.

The peninsula itself runs straight south in to San Jose which is the center of the 'South Bay' area.
That is not where you are staying.

Across the bay from San Francisco is the city of Oakland and the 'East Bay Area' region.
That is not where you are staying.

Most ladies who work in San Francisco will also do outcall to SFO,  Many ladies working on the peninsula also do outcall to the SFO area.

Hope this helps.
