We had booked in for 2 nights but we would have been happy to stay longer. We were made very welcome by Frau Kieser, who spoke good English.
The en-suite rooms, on 2 floors were very comfortable and clean, and included at least 2 singles. I believe an apartment is also available. The breakfast buffet was substantial, with a selection of cold meats, cheeses, preserves & spreads, orange juice, cereal, bread, cakes & rolls. No evening meals served, but 3 eateries nearby - a bar with burger & fries type menu, a sports club offering excellent reasonably priced meals (barbecue the night we arrived), and a hotel with an up-market restaurant specialising in fish.
The prices were very reasonable - under £35 per person per night, pre-booked and paid in full in advance. NB the hotel does not accept credit cards.
The small indoor swimming pool (5ft deep) was very welcome after a long walk in the Black Forest.
The hotel is situated in wooded countryside beside a babbling brook just off the road from Neuenburg to Bad Wildbad (both about 5 km away), behind the Gasthof Zur Eyachbruecke (which was not open). Some people find the sound of babbling brooks conducive to sleep but for others it may take a while to get used to. Off-road parking. Good hourly bus service to the above towns and less frequent buses to other locations. The hotel is beside a rail track, which I understand is being upgraded to provide an electric tram service between Bad Wildbad and Pforzheim approx. 21km away. Karlsruhe, on the Rhine, was less than half an hour's drive.
