This is a really fine hotel. We ordered a room (very clean and comfortable) with a view on the lake. (and the ferry boat just in front of the hotel) We were lucky with very fine weather to have a walk, and even a sunbath on the border of the lake, it was extremely fine.
The hotel is very ok. The food is delicous, and it's a "buffet formula", with fisch, meat, cheese, and so on..... I already had better kinds of buffet, but it wasn't bad at all.
What was very unpleasant is that we arrived at 20.45, being caught in a traffic jam for hours. We called (as they asked us) to the hotel to say that we only could arrive just in time before 9 pm. (then they close the buffet) Even after calling, and just in time, it was no longer possible to take dinner, and they served us hamburger with fries. Not bad, but a little bit of flexibility would have been fine.
A strong point was a cosy bar under the hotel, where we could watch football/Soccer. For those who love football, a joy to be there. Warn you wife! The bar outside the hotel is also very fine, with a view on the lake. For people who love to walk, and love a quiet atmosphere, this is the place to be.
