This place is fine but is unlikely to be the best stay for your money in Paris. It is a tiny room (even by Parisian standards) and two people are frequently on top of one another in this space.
Unfortunately, the hallway into the apartment was under renovation (we were not given any heads up about that). This meant there were no lights in the hallway to get in. We had to use our phone flashlights to enter/exit the building. The wifi was also not working while we were there. That might have been due to the renovations but neither the hosts nor their assistant alerted us to this either.
That said, the apartment was clean, quiet, and the location is good for walking to sights on the west side of the core. Less good for reaching le marais or the Latin quarter, but still doable.
Overall it was fine but I am confident we could find better for the value. Would be unlikely to stay here again.
