Both ways are used around here. At her address the meeting unfolds in absolute calm, with no noise and no movement around. The outcall, on the other hand, solves the travel and navigation problem in one go, and it's the one usually chosen by people living in more urban areas. Ask which she handles before going further.
Arranging is direct: you look at the profile, see photos, hours and services, and write on WhatsApp with no middlemen. Set out the format, the day and how long you have in mind from the first message, because improvising as you go is especially awkward here. With that sorted, the rest of the exchange is usually brief and free of back and forth.
As for what's on offer, there's everything from short meetings to long dates, massages and warm-treatment proposals, the ones advertised as a girlfriend experience. Given the journey, a long meeting makes considerably more sense than a brief one. What each ad publishes is what gets agreed, with no last-minute additions.
One quirk of this corner of the department: after several days of rain, the unsurfaced stretches turn heavy and some inner accesses get tricky. If the forecast looks bad, ask when you arrange how the road to the door is holding up; it's a normal question around here and it saves you a problem on the final stretch.
