My concept of an Airbnb is: staying at my home. But I didn't find salt/oil to cook. Neither soap to wash my clothes. And also I bought an opener to the bottles.
The stairs down to the kitchen can be dangerous if you don't have attention.
The street is so quite, but not the neighbours. At 6 or 7 am people can running down the outside stairs... And if you think having a rest after lunch, forget it. Behind the place there is a school (I think so) with noisy children.
The shower is amazing and also the location, near Gare du Midi.
