We visited in early August, just missed the fires outside the park.
Two families, nine people, ranging from 17 and up. Plenty of room, large bedrooms, everyone was comfortable.
The house and grounds were clean and well maintained. Although the neighbors are fairly close, it was very quiet. The Redwoods staff was very helpful.
Only possible downside is the distance to the main areas of the park, but if you're an early riser, travel should not be a problem.
House was well stocked with bedding at kitchen /grill equipment.
Excellent value and experience.
