I was there for a 3 days business meeting and the experience is quite poor.
Here are some facts :
No free Wi fi access in rooms, food more than average with the painting of the roof that needs to be refreshed in the restaurant room, my bedroom was supposed to be smoke free but there was a strong cold tobacco smell (I changed room), chairs in the meeting room are quite uncomfortable...nothing compare to the website that let supposed you will enter a kind of castle.
Last point, I didn't experience the the thermal swimming pool but it is on the back side of the building and is facing 1980' style residence...not glamour.
That's why I compare it to a low cost business hotel but unfortunately the prices are not low.
