Sorry no one's helped you yet.  There's plenty of fine ladies to choose from in SF, but here's my short list of favorites.  I've seen most of these ladies or have recommendations on them from friends.  They all are well reviewed and reputable and should help make your three week stay pretty enjoyable.  Most of these girls have websites with tons of information and pics.  Good luck.........

Stephanie of  San Francisco
Saw Steph last month and my time with her was terrific.  Beautiful body, great attitude, keen mind, and a wonderful and gentle personality.  Sees clients in the downtown SF vicinity and takes very good care of them.  First timers should know she requires a reference, but once past that, you’re off to the races with a winner.  Visit her website at  http://www.stephaniesf.com/ and drool over the pics.  Even better pics can be found on her Eros ad.

Lauren Nicole
Well reviewed and just about the best known lady in the area.  Five feet nine inches of female perfection.  Great lady, pure class, super nice person, outstanding body, excellent service, a great attitude, and rational prices.  No wonder she’s always busy.  Book ahead if your from out of town, especially if you want a dinner date type of meeting.  Everything you need to know about Lauren is on her website:  http://www.lauren-nicole.com/

Juliette
IMHO one of the most underrated ladies in San Francisco.  Gorgeous body, fair prices, offers doubles, a great boudoir wardrobe (with a fetish and vintage look) and first-rate  service.  I saw her many months ago and it’s on my list to return again soon.  Like her website says: ‘Embark on an Adventure’ at http://www.goddessjuliette.com/ and she’s well reviewed (very favorably) here on TER.

Auburn Fire down in the South Bay.  
I don’t know exactly what’s up with Ms Fire, but in the last 9 months, she’s been rated a perfect ‘10’ by no less than 12 different reviewers.  And all the rest gave her a near-perfect ‘9’.  Go ahead, check out her reviews here on TER.  She must be doing something right.  Here’s her website:  http://www.auburnfire.com/

Kristen D’Angelo is one of the most popular GFEs around these days.  Haven’t seen her myself, but I have two buddies who have seen her while on tour in NYC, and they regard her highly.  Both had a great time and rave about her.  Kristen tours a lot; you have to check her schedule or call to see if she’ll be in SF.  http://www.mykristen.com/

For something way different, there’s ‘Sinful Suzzi’.  www.sinfulsuzzi.com  Well reviewed on several sites, she’s totally popular (the San Francisco-version of Chicago’s renowned BebeDoll). Suzzi often plays in SF though she’s based in Sacramento.
