An hour lots of things can be done, plus the client doesnt have the pressure to leave and wants to make sure his time is relaxed and no hurry... In half hour things tend to develop much faster..
If we go by what you said above, less traffick in the apartment and attract the client to stay for an hour, charging 80/half hour , the hour should be less than 160 e, maybe 150, 140 ... 130... What prices are those one?
The best (sarcastic) news is client expects to pay 150, stay 1 hour if not more ,to receive advertised services and not advertised, a tea and a chat and why not a bath...
One other thing, the best client in my view is the one who come, pay and leave, dont moan about the price or about not getting a glass with water ...
Not to say the last, I am independent escort, I charge whatever I want and happy because I dont have a pimp to do my prices
