We stayed at Anne's place in the summer which was comfortable. Note that the house has single glass and could be a bit chilly in winter time.
We found that the previous visitors didn't clean that thoroughly, we saw that the place hadn't been hoovered in a while. My suggestion is - even though this is managed as a traditional Bach ('clean after yourself') not all visitors clean the same level and getting a cleaner from time to time could be useful.
Other then that we enjoyed the place, well equipped. Very easy check in. As listed, dvd player available connected to TV, so bring a nice dvd for the evenings.
