Su's place is perfect for a San Fran visit! Safe location, very close to a road of cafes and shops if needed without going into central San Fran.
The place is massive - really good space and it's clean and well decorated. We really enjoyed our visit to San Francisco and appreciated Su's hospitality.
If you do visit San Fran I highly recommend driving north of the Golden Gate Bridge and visiting Sausalito. Such a beautiful town with amazing ice cream!!
