Most of what is said in that article is true to this day. The girls do not get many clients and they do seem kinda desperate, however, the club is still a good choice if you are looking for FKK in Wien. Just keep in mind that you do not have to settle for any deals that the girls are offering. (such as TRIOs)
If you are not easily persuaded and you know what you want, Goldentime is still a good choice.
