We staid for 1 week at Hotel Bergblick in Bernau in the Black Forrest. This is a family run hotel with a very comfortable and relaxed atmosphere. We had one of the suites "Room Distel" which was really nice, newly renovated/decorated and spacious. The bathroom could be a bit bigger and provide more storage but otherwise clean and functional. The room had a big flat screen TV and DVD player as well as a very large balcony.
If you don't speak German you will have some problems in communicating, although some of the employees try their best you wont be able to even order a meal in English. The location is very good for outdoor activities such as mountain biking, hiking (Nordic walking) and in winter for cross-country skiing.
The hotel has a good reputation for good food, however we did think that it was rather ordinary. To their defence I have to say that we had the full board option and I believe if you ordered al a cart your meal would be much nicer than the full board menu.
All in all it was a really nice country hotel in the middle of the southern black forest, which I can recommend.
