Since I've visited them late at night their look were not exactly as in those fancy photos. I mean in terms of preparations and make up, but don't get me wrong they are real like in those photos. Both of them are above average in terms of beauty and body. Dana has great tits and Milena has a great body with curves. She has also a pretty face, if you look close enough it resembles Keira Knightley in some way :)
Their English was not perfect but they usually understand you and try to answer in a good way. I didn't have any major communication problem with them. Dana was a little bit shy at the beginning but caught up the tune later... Milena is really good in GFE.
The service was great, they are kind and try to do anything you requested (this may not be the case for every client though). Milena was more active during the sex and Dana was in more of a support role (dunno if she is more active when meeting one-on-one).
In summary I recommend both of them. If you can try to visit them together since they are a great duo. Otherwise chose one and enjoy!
