If you are looking to crash at night and take some rest, a living room mattress is available in apt complex. Next to BART, 5 min Walk to Workday, kaiser Permanente, Deloitt, Abott etc. Next to Stoneridge Mall and BART (commuters dream to SF).
This is good if you just like to stay over night, not for long stay. Comfortable for one person as mattress is on floor.
