Is this only true for V in Berlin of also Düsseldorf?

Never been to dusseldorf but i am pretty sure Berlin is different and better as the city has got a different vibe and more tourists, students etc.

Anyone has been in TE during the weekdays? how does it compare to weekends?

one day in Sauna
 

After a short bike ride, I decided to spend the afternoon in a sauna in the capital of Austria. Upon arrival, I did not notice any younger people. I have to say that summer in saunas in Vienna is very boring. Only elderly people. After about 2 hours, however, I noticed two interesting young people. It was a young couple of guys about 28 years old and a girl around 20 years old. After about 15 minutes, I noticed that they entered the sauna. After 10 minutes they came out and I just went around the shower - The girl was pretty, she had white skin, blond hair and big breasts. Her pussy was gorgeous, completely shaved and only had a line. After about 1 hour, the wild girl became completely shy and started walking completely naked from the lounger to the pool. I thought she was showing off and showing off. she combed her hair and stood completely naked and I just watched her for about 20m. This was just a small experience.....

Can't say about TE, but we went to castle-sauna yesterday. They have a 50% student discount, but still the average age during weekdays is way higher than in the weekends.
My guess that only 2 students were actually there, then 80% old people and some 30-40 year olds.

Vienna has many places to be nude in summer, especially the Donauinseln. Most young people will be there.

Frankfurt and surroundings?
 

How about Frankfurt, any good places?

What about Titus Thermen? Rhein-main-thermen? Thaunus Thermen? Panoramabad Bornheim? David Lloyd Club Frankfurt Skyline Plaza has a fitness centre, that may attract the right crowd? Kur Royal? Saunagarten Röder Thermen? Die Sauna Erzhausen? Riedbad Bergen-Enkheim? Rebstockbad?

Whats the deal with TE?
Do people walk around wrapped in their towel? Do people lay on the loungers in towel or nude?

If the weather is nice enough to be outside on a lounger then that area will typically be full with everyone laying out fully nude. The walkway to/from the outdoor sauna area is directly in front of the lounging area (which is only two rows deep). As such, the views are up close and personal. I only wish I could walk more slowly!

Most people walk around wearing a robe but there is 10% of the population (of both sexes) that enjoy peacocking - and that percentage does increase two or threefold as alcohol is consumed on Friday and Saturday evenings. But even without alcohol the aufguss sessions will conclude with dozens of overheated nudies spilling out into the Amsterdam air to consume water, shower off and generally stand around undressed in an effort to bring their body temp down. That TE pulls in a young-ish crowd of local, well-toned bike enthusiasts only adds to the charm. IOW, it is not to be missed on any trip that lands you within 100 kilometers of Amsterdam.

Is TE the biggest or most luxurious wellness center? Heck no. But what it lacks in luxury it makes up for in countless other ways.

Pro tip: bring your own robe and flip-flops (thongs) to save money and to help you distinguish yours from the dozen others that were left outside the sauna.

Enjoy!

Normally TE refers to a place near Munich. What place in Amsterdam are you talking about?
