It's important to note that "student apartment" is a euphemism for rundown apartment. Old furniture is fine, but when none of the doors in the apartment (bedroom, bathroom, closet) can close because the floor is so warped, that's another issue. The front door only closed if deadbolted because the door jam was so loose that the latch couldn't latch.
The bathroom ceiling was dirty, and the bathroom fan, as well as the other fans in the apartment, were full of dust. The kitchen had a coffee machine, but no kettle. A kettle would have been more versatile. Half of the outlets in the apartment were unusable because the outlets were loose.
After my first night I asked for an extra blanket because I had been cold. The response: no one could bring me one.
Pluses: lots of natural light, place larger than expected, bed comfortable, location was great (near Old Quebec and downtown).
I wouldn't stay again. Just tell clients the place is rundown. They can then make a more educated decision.
