Take 280 or 101 to 92. The first exit off 92 east of 280 is Ralston.

Go 7/10 mile down Ralston to the "Belmont Canyon/Hillcrest" intersection. It's the third light -- first light is Christian, second light is Hallmark. Go north (left, assuming you're coming from 92). At the stop sign, stay right. Go 3/10 mile and the house is on the left at a sharp right bend.
