The house is great, and in a beautiful location. The room is absolutely clean, and there are all the amenities which you could want - there is even a kettle so that you can make your own tea or coffee.
The bathroom is separate from the bedroom, and like the bedroom it is spotlessly clean. You have a separate entrance door on the same level as the bedroom and bathroom, so you don't need to disturb your hosts when you arrive and leave.
The views are amazing from the house, and the village of Champagne is very nice, and has a restaurant and a café at La Fabrique for breakfast.
Domizia gives great advice on where you can travel and what you can visit during your stay in the region.
The only downside was that there is no parking at the house, and you need to use the (free) public parking around the corner - however, one evening this was full, so the only other public parking in the area is paying (CHF 10 / 24h).
I would happily stay at this place again whenever I visit the region next time.
