These are the issues
1. very few hangers or places to hang towels or any clothes.
2. The host’s helper does not speak English
3. There were no sheets or pillow cases on the bed.
4. There are only 1-2 coffee pods and tea bags
5. The neighbors are very noisy.
6. You have to go up a ladder (not a staircase) to reach the bed, and you cannot stand up in the loft.
However, not really knowing if this is standard for Paris…the location is ideal!
