We stayed for one night in a weekend. The bar music was loud until around midnight. Which was reported to reception at checkout. We were also unfortunate to have some louder neighbours keeping the party going well past 1am. Reception told us to definitely call then straight away next time. They have security just for this purpose.
We also decided to go to the wellness Sunday before noon. The lady at the desk was French only, talked enormously fast. Just went over the amenities in record speed. No questions whether we had experience with those particular amenities.
On the topic of amenities, no wellness music was playing, except in a sort of backroom where they store employees stuff and vacuum cleaners. The door to the Finnish sauna plainly doesn't close. A lot of calcium deposits were found on all available showers. The windows of the outside jacuzzi were so stained, you could barely look through them. There also is some loose woodwork trim at the jacuzzi roofline. All in all not terrible, but they need to go over that place and do all necessary maintenance.
The massage we ordered was very good.
If you stay the weekend and also want do go to the spa before noon, I'd advise to not reserve breakfast at all and hold out for the Sunday brunch. Vast food options, bubbles, wine, fresh juices and sodas as much as you can drink. Fresh bbq meats with amazing vegetables side dishes, a cheese and charcuterie table and tons of dessert and coffee options. The only 'negative' part I can find here is tgat a lot of staff are stationed by the beverage options to help customers, but the placement is in the narrowest and busiest path of the lunch room. If they'd move it over to the fresh juice station, people would bump into staff far less than what I have experiened and saw while I was there.
