There are a couple differences between the Olallie Lake Resort and its facilities vs The Olallie Lake Guard Station Cabin. Although near to each other on the lake, and both managed by the  resort staff, the Guard Station Cabin is owed by the Forest Service. They do not allow pets in the cabin or in your car when you rent it. 

The resort rents a number of rustic cabins themselves, along with two yurts, and operates a number of nearby campgrounds, the store, and the boat rentals.

The Guard Station Cabin must be rented from Recreation.gov , and has much less basic facilities, kitchen with hot & cold running water.  Propane powered stove/oven,  refrigerator , and built in lights.  Pit toilet nearby,

I believe the other reviews refer to the resort's cabins.
