The spa is known for its pools. Water is from a local well. Expect a variety of whirlpools in and outside. Bathingsuit is mandatory. If you've forgotten, you can buy one on the spot.
There are also massages and treatments possible. The options are not cheap, so keep track of your spemding to prevent surprises at check out. Visitors seem mostly couples.
The spa itself is nice, but can get crowded over the weekend. Try to stay away on friday eve amd the holiday seasons. Definitely give the whirlpool a try, dead sea bath etc.
Overall, i liked the thermen. Definitely nice for a break.
Tip: check out deals on the website and boom your treatments well ahead. The thermen are not cheap, and it may be worthwhile to bring your own bathrobe, towels.
