Stayed here for six nights on half board.
It's quite a small hotel but has an attached campsite with extra leisure facilities. The campsite was very quiet despite being quite full (this was mid-July).
Room was a good size for a couple, with a comfortable bed, balcony with lake view, and a good sized bathroom with an excellent shower. No air-conditioning, but has good ventilation through the balcony doors/shutters and we were comfortable even though the weather was very hot.
The half-board was a very reasonable extra; three course dinner was basic but tasty and lovingly prepared. Typically we had a traditional Austrian soup to begin, followed by a choice of main course, and then a dessert. Neither of us wished we had gone "al la carte" - even though we eat out a lot.
The service was really excellent; the waitresses were traditionally dressed, spoke good English, and were really quite charming and very helpful.
Buffet breakfast was typical continental; ie. fruit juice, cereals, yoghurt, fruits, cheese, ham, rolls, eggs, toast, coffee/tea.
The setting of the hotel is unbelieveably good; stunning view of the lake and mountains and plenty to see and do locally.
The hotel provides plenty of sun loungers for guests to take out to the lakeside which is just 30m away. There's a jetty with steps at the end that makes getting in and out of the lake for swimming easy.
Overall it's hard to imagine how our stay could have been improved - really excellent.
