I have been to Artemis several times, though not in about 2 1/2 years. It was, by far, the biggest and best club in Berlin, and probably still is. If I recall correctly, the charge for entry to the club was 65 Euros, and sex was 60
Euros per half hour, though that may have changed by now.
First of all, let me say that you do not negotiate with the women there. The prices are set by the house. You either pay or go home. Extra services, like CIM, cost extra, but again, the price is set by the house.
Also, you are not actually naked. When you go in, they will give you either a robe or a towel to wrap around yourself. I forget which of those Artemis uses. The women are naked!! (Yes!!! Thank you Lord, and please don't strike me blind just yet!!!)
As far as advice is concerned:
1.Google their web site, and take a look at what they have to offer.
2.You cannot touch the women sexually (without paying that is). You can shake hands or give them a friendly hug, but much more than that is a contract, and you owe them money. If you DFK, that is a contract, and you owe them money. They can touch you unless you don't want them to, but then why are you there in the first place?
3.Take your time. Do not run off to a room with the first woman to reach under your towel and stroke your crank. You might find one you like much better in a half hour.
4.Talk to them about what you want and what they povide. Some do DFK; some do not. If they do, it should not cost extra. CIM and anal do cost a lot extra, so be sure of what you are getting befor you start.
5.Watch out for sharks. Most of the women there are honest, hard working women just trying to make money while having fun, but a few are upsellers or just plain cheats. Upsellers will try to get you to buy extras, like a second half hour for example. They charge by the half hour, or any part, so if you go 35 minutes, you owe them double. Check your watch when you go in the room so the cheats cannot say you went 35 minutes when it was only 25.
6.Bring super glue to glue your eyes back in when they pop out of your head.
7.Have fun! Think of me! I wish I was there too!
Dixmore pretty much gave you a dead on account of what to expect. I was there in the middle of July (20009) and it was my first experience of that type.
Price of entry is now 80 euro and oral and intercourse is 60 euro for 30 minutes. Do not base your expectation on the pictures of the girls on the website. Thoses pictures in my opinion are not an accurate representation of the girls. The ones that were there (a Thursday night) were exceptional. It was like going to a high class strip club in the states---a lot of girls were super hot.....worst I saw were average girls but definitely something for everybody.
I was with a Polish girl and Bulgarian girl. Not at the same time but that can be arranged too. I was blown away (pun intended) by these girls....absolutely fantastic experience. Definitely a good way to broaden your European experience. I would recommend taking a taxi to the place if you are not familiar with the area.
The cleanliness of the club was good as well. It was a very nice experience and worth repeating. If I wasn't so tied up with business I would have repeated every night there.
In closing, I would like to say that it was fun and I liked it.....
