Jia's place is definitely worthy of consideration for a traveler visiting San Francisco on a budget.
The price is reasonable for San Francisco standards. Not only that, it is location, location, and location that makes this Air BnB outstanding! There is a Safeway just one block up for your grocery and other daily needs. A coin laundry business is located right next door to Jia's place. In terms of public transportation, the MUNI bus stops (23, 36 and 43) are very close with Glen Park BART Station located six or so blocks down Monterey Blvd.
To summarize, Jia's place is worth every penny that you pay for. Highly recommended.
