We had an appartment with two bedrooms, and the only flaw we could find was the fact that it did not have a balcony. So next time, I would definitedly ask for one with a balcony. Other than that the bedrooms were very spacious and well equiped. The basement area with tabletennis and pool billiard was great on rainy days. And the fact that wifi was only available in the basement actually motivated our kids to use the tabletennis more often. Where as I would have guessed it would work the other way around ;-)
The owner was very friendly. Parking is easy, plenty of space. You do obviously need a car, since it is quite a way out of the village.
We used it as a base to walk parts of the Schluchtensteig.
