The profile carries the photos, the hours she works and the breakdown of services; it's the source of almost all the information. What follows is a WhatsApp exchange, always directly with her, with no middlemen or third parties running the diary. A short, concrete first message is usually enough to find out whether she's available.
Besides hosting at home, several also do outcalls: they come to your place or to a hotel in another area, since that option doesn't exist here. It's a practical choice if you live nearby, or if travelling is easier for you than hunting down an address among short streets that look much alike.
What's on offer varies from one ad to the next: short meetings, longer sessions, massages, and also warmer arrangements of the kind advertised as girlfriend for a while. Some girls add companionship for an outing beyond the neighbourhood. Asking about something that isn't listed is fair enough, but her answer is final and isn't up for debate.
To arrive, the most comfortable route is to get off on one of the edge avenues and walk the last stretch; it's only a few blocks and nobody notices a pedestrian. By taxi or ride app it's the same, with the advantage that you don't have to worry about where to leave the car or how long it stays there.
