This place has been in the news quite a bit recently due to a legal investigation into the way it was financed. However that may be, the resort has many things in its favour - starting from a beautifuk location right on the edge of the lake. You can swim, boat or just enjoy the view - we opted for the latter, given that our visit was in autumns. This also meant the place was't too crowded, and the sun standing low on the mist-covered lake made for a beautifuk atmosphere.
We had booked an arrangement that included some spa treatments, as well as the use of their two (smallish) saunas and the steam room. They offer a variety of exercise classes as well, some of which we took and enojyed very much as part of our arrangement.
While this left us quite relaxed, there are a few ways they could have done more to contribute to that relaxation. The heating in our bathroom failed repeatedly, which eventually made them upgrade us to a very nice superior room. There, though, the ac in the actual room wasn't quite efficient in warming the place up (which stands to reason, given that the vents are under the ceiling and hot air tends to rise). Other things I'd want to work on is the 10 euros they charge per night for parking (we parked in the road) and some service issues: For example, if a spa treatment is part of your booking, they allot you a time slot rather than ask when it would suit you.
Prices are reasonable given the beautiful location and the layout of the whole place, and the breakfast they offer is in a league of its own, with every hot or cold, sweet or savoury dish you might want. During the off-season, it's easy to get a table with a beautiful view of the lake.
Not sure how crowded this resort is in the summer, but for autumn or winter I can recommend it for rest and relaxation.
