Cheap, but not so cheerful. I stayed in the guesthouse across the street, which was fine, but very dated and a bit grim. Bathroom was grubby, with a lot of mould. Didn't look like it had had a good clean I a while...
The place was a bit creepy to be honest- a lot of cats in the building, which were loud, and made the place smell a bit funky.
It's fine for an overnight stop, as the beds are comfy enough, but if staying in the area for anything other than the bare minimum, I'd carry on up the road 2 or 3km to the town of Braunfels (really nice place)
