I loved this hotel, and had a very happy and relaxing one-night stay. My main goal was to go somewhere with a pretty view where I would feel comfortable spending some solo retreat time, and this hotel exceeded my expectations. The setting on the lake is absolutely gorgeous, and my room had a very comfortable space to sit and read and enjoy the view and the rain. I was also very impressed by the attention to detail in the rooms, which I much appreciate yet rarely see even in the fanciest hotels -- there was a yoga mat, umbrella, and hiking backpack, among other things, available to use in the room, and even a candle to light! I thought the breakfast spread had just the right amount of variety, and the coffee was delicious. All the staff I encountered were also very kind and helpful.
Note that the closest train station is Traunkirchen Ort, not the main Traunkirchen Bahnhof. I didn't know this and travelled in and out of the Bahnhof, which is a 20-minute walk along the highway/lake.
