I recently stayed a night here on business. The hotel was very clean and well kept but a bit tired. It was also hard to find someone to check in with when I arrived. That said, the nature reserve around it is wonderful, and sleeping there on a warm summer's night with the window open was lovely. And the grounds are really nice- wish I had had a bit of time for a wander.
The restaurant is a real gem. The service was really friendly and attentive and the food was phenomenal. I haven't eaten that well in a while- and the local white wines were a treat too. I'd stay there again just for an excuse to go to the restaurant!! The breakfast was a nice German breakfast buffet with plenty of variety and really nice coffee.
I was a bit unsure about internet access- they said they didn't have any but perhaps the guy at the front desk misunderstood me- it turns out you can buy access to a T-mobile hotspot for a really reasonable day rate. Connection was good too.
