Stafford Cabin is an 1880 homestead log home on the Silver Spur Meadow Trail in Bonita Canyon. I'd make it part of the walk through the Faraway Ranch Historic District and meadow, not a separate drive-up stop. The trail is 1.2 miles and usually takes 45–90 minutes, with starting points at the visitor center, campground, or Faraway Ranch picnic area. The cabin is about 450 yards from the Faraway Ranch house.
The path is easy and fairly level, but it dips into washes and isn't suitable for standard wheelchairs. Wash crossings can be hazardous during winter snowmelt and summer monsoons. Leashed dogs are allowed. Interior access isn't confirmed, so plan on seeing the cabin from outside. The Faraway Ranch parking area has a restroom and water-bottle refill point; those aren't at the cabin.
