(SF) Looking for a furnished 1 BR apt/studio in SF

Hi everyone, I'm looking for a 1 BR apt / studio in SF, with a 3 to 6 month lease. I'm flexible on lease length.

I'm a male from Stanford CS, working at a startup with stable income. No pets.
Quiet, very clean, and not a partier.

I'm particularly looking for locations near:

• Western addition / Haight-Ashbury / Hayes Valley / NoPa / Pac Heights
• Russian Hill / North Beach

or adjacent neighborhoods.

Let me know if you have anything that might fit. Thanks!
