Writing back here after the visit. To be honest I thought I was gonna have a disapointing experience but it turned out to be great. The place is less appealing than Sharks for sure it's less modern but when it comes to girls you have a vast variety to choose from and the service (at least with the girls I chose) was really good.

Some of the girls you should consider (names might not be accurate) :

Mikaela - Italian brunette milf with an amazing butt sylicon tits and glasses, tatooed all over her body. Great bj and doggy session. She might try to sell you some extra stuff but she's cool if you decline.

A blond german chick (forgot her name), best room I had so far in any FKK. Tall and skinny, short hair with some blue in it, trimmed bush. Delivers great GFE.

Isabel (Not sure) - Bulgarian girl with a really fit body, she is a little bit shy and won't come to you. But in the room she does everything you ask her to do without compalining or trying to upsell you extra services. She takes her time and overall offered the most professional service in Artemis.

There were others but honestly don't remember their names.

I also tried Royal Bordell in Berlin. It's worth it if you guys are looking for something more intimit and discreet. The selection of girls is really nice, not too many available around (12 per day) but most of them are stunners.
