Looking for SF or Peninsula sublet, fall quarter

I'm a PhD student doing an internship in SF during the fall quarter and looking for a sublet or other short-term housing.

I'm interested in anywhere from SF (especially near Bernal Heights) down the Peninsula (as far as Menlo Park), and would prefer a furnished 1 bedroom apartment or studio.

Dates: roughly Aug 20 - December 31, but very flexible on each end and interested in continuing through the winter quarter
