I was in Prague few weeks ago and they didn't respond to my messages.
I think that's the main reason, but from my experience in Prague, some Privats have a more overall customer friendly approach and they also hire girls that work according to this approach.
Let's say that sexinprague is not one of those Privats.
Nevertheless, I have visited this Privat, cause the appearance of some of the girls, are superior from other budget friendly Privats.
I know that most of the Czech members don't share my opinion, we have discussed this subject before,
but as a tourist, I don't have the time or the Czech language knowledge, so that I can find the hidden little gems.
No offense, but If you compare in terms of age and appearance, for example the line up from Mazlive Studentky and this of Sex in Prague,
the difference is massive and I personally have no problem to overpay 1000czk in order not to fuck a girl that I wouldn't even notice at the streets.
The only argument that I take in consideration, is that some times the same girl that you fucked with 1500czk,
has suddenly a value of 2500czk when she is hired at a more expensive Privat.
In any case, I will be on Monday again in Prague.
Last time I didn't wrote any reviews, cause I talked at Tesco to an Irish girl and I spend the days with her.
