Smith Creek Village cabins are comfortable, but definitely not posh. Our cabin had two twin beds, a bathroom with a shower, a tv, a coffee maker, a refrigerator, and a microwave. It is conveniently located near the Big Leaf Coffeehouse and a short drive from South Falls.
Food options at the park are limited (the reason for the 3 stars for service) especially during the week, so be prepared to either drive out of the park for dinner, or bring something to microwave most days. Bag lunches can also be ordered in advance, and I believe South Falls Cafe (near South Falls in the park) serves food daily from 10 am until 4 pm daily. The new Big Leaf Coffeehouse serves dinner on weekends, breakfast on weekdays, and a Sunday brunch. Of course, these may change over time and perhaps by season, so check first. The reservation people were very informative in this regard.
We were pleased with the accommodation overall. Nothing fancy, but this is rustic park accommodation. The cabins are reasonably priced, clean, and comfortable. Being able to spend time at the Falls and relax in our room afterward was well worth it.
I have stayed at the cabins several times over the past decade and would definitely recommend them.
If you want a slightly more "Temperate Rainforest" experience, ask for the Upper Smith Creek cabins, a little further out in the woods, with a shared shower facility and outside firepit (fires may not always be permitted).
