Undergrad looking for housing in SF & campus

Hi,
I'm an undergrad looking for housing for two internships this summer:

SF — June 15 to Aug 22, for a summer internship at 220 Montgomery St (Financial District). Ideally somewhere with a reasonable commute downtown.

Stanford/campus area — Aug 22 to Sept 20, while I'm doing research on campus
.
Open to subleases, a room in a shared place, or anything in between for either period. Please reach out or pass this along to anyone who might have a spot! Thank you!
