I enjoyed my stay at Joffrey's place, the apartment was nicely decorated and the host was responsive, it was easy to get in.
I did think the price was quite high for what you get (of course this is Paris). I was here for a week of work and if you are too there are a few things that I would take into consideration before booking. The Wifi was not great and did not work or was really slow, the amenities listed were not all there (shampoo, shower gel) and after using the shower or the sink in the bathroom it started to smell like the sewer. The place was not super clean and the sheets, although washed, had stains on them. The neighborhood is okay but as a woman it felt not great to walk alone at night.
