Natasha.

Silicon Valley has lots of AAMPs.  Check out Eros to see particulars.  Positives is that you can schedule last minute in a convenient, safe location.  Negatives is that very few of these will be top-floor experiences though you get your money's worth.
When I travel I usually check the local eros offerings and make sure that whoever interests me has some solid reviews.  And, of course, you can always look here.
If you want two solid providers, you can't do better than either Natasha and/or Porscha.  Both have great reviews here and both are $$$$.  Allow a couple of days for the referral process.
