The cabin we stayed in (19) was a bit aged. There was only one key and no deadbolt. The carpets could use cleaning and the toilet was very small, old and not attached to the floor completely.
It was nice having a refrigerator, stove/oven, microwave, and dishes/pans, towels, and soap/shampoo.
There was a new queen-sized sleeper-sofa. Unfortunately, sitting on the sofa was as about as comfortable as a concrete bench. We did not test the fold out sleeper mattress. Fortunately the two queen-sized pillow-top beds were comfortable, as were the pillows (3 on each bed).
We knew there is no air conditioning but we were unable to open the windows in the bedroom to get air. They did provide fans, which helped a bit.
