I sent Teresa an e-mail, in Spanish, received a reply, in Spanish, the same day.  She quoted $220 for two hours and $310 for three hours.  She wrote that she would "treat me like a King."  She said we could meet at the "corner" directly across from the turnstiles??  If I see her, hard not to spend my hard earned $$$ on Renata and/or Nicole - whom, by the way, will do twosomes - but the "Mona Lisa like face of Teresa" is simply too good to not take a chance.  Will post a review if I see her.  I'd also highly recommend Rosa Mesa in Ensendada (find her at Antonio's bar), no Internet site, a beautiful, thin, tall Chica who fucks like a bunny for all night for $1/2.  Fluency in Spanish makes Mexico a tremendous bargain for we hobbyists.
