Do you need a contact for arranging punts in Warsaw?
I've been so many times, now I have a rotation of "regular" girls I like to visit.
I do still however have a local guy that arranges punts for me if I choose to go "off menu". I bung him a few euros and he makes calls for me if I need them. He's actually the 3rd guy I've used for this service after the other two disappeared for various reasons.
I agree with you that it can be difficult to arrange punts with some women, since many do not have WhatsApp etc, however I have still managed, with a lot of effort.
You need to be patient, plan ahead and have a local SIM.
