The cabin is the original cabin where workers used to live. It has been extended (but not renovated).
Its a real farm stay, great views from the window, horses, dogs, very private, etc. Not "rustic" though, whatever that means. Think of "old" (like "the front door doesn't lock" old) and very basic kitchen.
To be fair, the beds are nice, the views are nice, one the dogs is very friendly, it's conveniently located for day trips, and it's a fair bit cheaper than other options. As long as you don't expect "rustic", you'll have a ball.
