You are right and I must say that in Prague with metro and trams you are within minutes almost everywhere.
But as a tourist, I have experienced that when you what to visit Privats,you must have many alternatives.
Because sometimes Privats cancel the appointment or the girl is ill and went suddenly home or you see the girl and you are disappointed(fake fotos,age,etc.)
It is very different if such things happens for example in escort69 which is very far from where you stay and there are not other options in the area and it is different when you are in Prague 3 and walking distance to Μazlive,Grace,SexNo1,TopPrivat,Fascination,etc.
If something goes wrong with one Privat,you always have a quick alternative.
I have just booked an apartment for 31Jan-1-2 Febr,right next to SexNo1
I was last summer last time in SexNo1 and I have paid 1500Kč/hour but now I see that it is 1800 Kč.
I also read in tapky that Aria,Eva,etc have fake fotos...
So....There will be no SexNo1 for me this time.
I also thought that Fascination is the new Lolitas,Geisha,Lucerna.....but unfortunatelly it's not.
It is too early to search for my options...
I always wait to see the Calendar from the Privats to see which girls work the days that I visit Prague and then I decide...
And if I may, I would like to give some advice to tourists like me..
When you want to pay for sex in Prague,there is only one option,the Privats,especially the well known Privats,with websites,Viber,Whatsapp,English communication,etc.
FKK,Strip Clubs,escorts,etc. is someting that I don't recommend in Prague.
If you want to fuck an Ukrainian,Russian or a Colombian,Venezuelan girl in Prague and pay 200-250euros, you can fly for 50 euros to Kiev or Barcelona and fuck them there in Studios for 50 euros/hour
So..Think also the local guys and don't overpay for sex.
The point is not if you have the money or not.
The point is that overpaying is stupid and ruins the local scene
