For a start, the room descriptions are misleading - notice despite there being 32 pictures posted, none are of the actual rooms (or the stairs). There are not deep soaking tubs in each room, or even separate bathrooms at all. There is ONE bath, ONE shower room and ONE toilet. They are separate, but shared between all rooms. The rooms are tiny, we barely had enough room to walk around the bed once our we had our bags inside. There are radiators along the wall, but no air con, we slept with the windows open but it was still stiflingly hot. All the bed rooms are up a sleep and narrow flight of stairs, quite awkward if you have a big/heavy suitcase.
There's parking onsite, but its basically just where ever you can fit your car in the driveway. We arrived early and almost got parked in by families with huge vans.
Unless you came to Biei to stay in a Euro-themed guest house for some reason, there isn't much to recommend Kunshaus. It's over priced compared to other places I stayed in the area, and the facilities are very limited.
