We have booked an overnight arrangement with sauna entry and dinner.
The thermal bath has a couple of nice and unusual saunas. Also special was the salt water pool, which looked like a cenote.
The hotel is connected to the thermal bath by a tunnel. This made it easy to go from the hotel room to the sauna in a bathrobe.

What we didn't like so much is the fact that the saunas are noisy.
The inner saunas in particular did not have a vestibule or similar again. which would have contained the outside noise somewhat. Complete relaxation was therefore difficult.

When we paid our bill on the day of departure, we found it negative that we had to pay extra for the side dishes that we were served with dinner.
It was of course not a large amount, but I do not expect any hidden extra costs for a complete package that has already been paid for.
The reservation for a beauty treatment was also charged extra. In my opinion not okay or you can tell it beforehand.
