The program "sex in exchange for accommodation."
Really, get rid of this student. This is the same case when dreams are better to remain dreams. Because it’s actually hell, in most cases.
In the morning, they will wear around the apartment, trying at the same time to learn, hair, color, eat breakfast, dress and go out on time. Even if you can get involved in this, they will perform their duties without breaking away from everything else. Then they study, the morning history is repeated in the evening, but already with hobbies, training, dates and more. Remember about “debt” they will be most often in those moments when you are sick, tired, you have a deadline or just don’t want to. And they throw with double dust, because of a sense of guilt. Plus to all this, girls’ hysterics and fears, plus family, friends, boys, and even these days.
You can give almost 100% guarantee that after a few such rentals you will only allow boys, or family couples, paying on time. No personal relationships.
