This property is gross:
Yes, the bedroom is humid -- what no one has mentioned is the constant stench of raw sewage waiting from the bathroom. It is unable to contained by closing the door and doing this only placates the situation for perhaps a day or so. As the days goes one and people in the building wake, the stench increases. There is an overall poor air quality which results in the pull out bed being the most optimal of the two options for sleeping.
The property was also in general disrepair with the stair barricade, an oscillating fan, one radiator and the entry door showing signs of physical damage.
The radiators eventually make popping sounds no matter day or night. They're also situated under windows that have a draft with curtains (a fire hazard when closed over radiators) so you will need to strategically warm the unit.
There is no security beyond the key that opens and closes the apartment. A drunk, angry passerby spent his time entering and exiting while yelling all night during our stay.
The washer advertised is also broken.
The host is unresponsive unless you are checking in, asking about check-in, along small commentary about seeing Paris sights, or checking out.
We're actively involving AirBnB and our banking institution for restitution.
Note for calibration purposes: we are foreigners that traveled to Paris for a holiday.
