Laurent’s appartment is small as an individual bedroom. We have to turn the bed into a sofa every time to open our luggage. The toilet is also very very small.
It has lots of cookware, and there is even an iron and an umbrella, so if you are ok with the size it can be quite functional.
For us the main problem was that there was nothing to ventilate the room (it was clear that there was no air conditioner but I expected maybe a fan considering the heat in Paris). The place was very difficult to ventilate as the only window is on the street, so the nights were extremely hot and quite suffocating.
Despite that, Laurent is very nice and answers very quick, so to sum up, it could be ok, if you do not mind the size and it is not summer.
