First, the before's (all photos from Georgia MLS):
To start, I know this detracts from the cabin vibe, but I would blow out all the interior paneling with some warm white paint. I don't feel a cabin has to feel like a cave and that would brighten things up considerably. I wouldn't change much at all in the living room other than some new, white slip covered furnishings, I love that wood stove!
In the kitchen I would paint the lower cabinets and take all the uppers down. I would probably take out the range and put in a base cabinet that holds a microwave and then install a cooktop. Some open shelves above and dark stone counters and call it a day. I'm thinking something a lot like these.
It looks like the bathroom has a good head start with hex tile floors. Just painting would be easiest but a subway tiled tub enclosure would be nice too.
And that deck would be perfect for morning coffee. It may be a pipe dream but it sure is a pretty one.
