We booked in with our daughter and her (then) boyfriend for dinner and an overnight stay.
The setting is idyllic, the rooms comfortable (and great that each one is different). Dinner was staggeringly good, probably the best lamb we've ever eaten, cooked over a wood fire. Prefacing this was excellent and abundant foie gras, following it a selection of local cheeses. Wine flows (made on the property), a digestif and/or a tisane to finish make booking a room a wise decision. Hate to copy what you've suggested in the "title your review" but, yes, we did love it and we will go back.

Stayed for three nights and thoroughly enjoyed it. It is only minutes drive away from Carcassonne, minutes off the auto route.Cavanac is a small village which didn't appear to have anything going on there apart from the Chateau. Arrived on a Monday when the restaurant is closed and it felt like we were the only people there! Had the pool to ourselves. Went for a walk in the vineyards which stretch for miles and you can see up to the Pyrenees, very beautiful part of the world.
The rooms are huge - we were in Oiseau de Paradis and was very comfortable and had a private balcony.
Breakfast may appear expensive at 12 euros but had the best selection of all places we stayed at.
The real treat was the restaurant. We had the full 6 course 42 euro dinner one night , the next night we had shared a starter, two mains, two desserts, coffee and one bottle of wine was only 12 euros less than the night before. The a la carte menu is only available to hotel guests. The restaurant was busy both nights with non residents which shows how good it is.
All dishes were superb, of excellent quality, great service, the house wine was very good. Look at the website for the menu.
The only slight gripe would be that the free wifi was only valid for 4 hours at a time so had to go back to reception to get a new passcode!
Not cheapest place to stay but when weighed up against the quality of the service , the environment you are staying in and fantastic food it was worth every penny.

Just loved this place. So relaxed, spacious, beautiful and way from hustle and bustle. Never stayed in a place like this before. Ensure you are there a night when the restaurant is open - def should eat there one night anyway.

The rooms are all beautifully decorated and each have a name of a flower. Ours had a four poster bed and the drapes were so colourful and sumptious. The food was fantastic. You have a menu if you are staying and the value is great. The wine is from the vineyards of the chateau and it was so good we bought cases to take away with us. Our family were visiting from Singapore and they loved it too. Very very peaceful
