Good:
-Location (very close to Metro)
-Bed is comfortable & large (for 2 people)
-Great host with good tips for restaurants & very fast communication
-VERY QUIET NEIGHBOURHOOD! (We slept with the windows open and apart from the mosquitoes we weren't bothered XD).
To note:
-If you're larger than 170cm you might find yourself bumping your head entering the appartment or the kitchen
-Cleanliness was okay, but not superb
-Cost to value ratio is okay, but there is better
-The kitchen is a pain in the ass to use: back stove is either 100% on or 100% off, silverware & plates/bowls are very old and needed to be cleaned before use, Pepper was missing
When visiting Paris: I recommend to get a place as central as possible. Then you don't mind walking around when it's dark since your trip back isn't long with the metro.
Considering all this our stay was good and I would recommend this place for people who don't have very high expectations but value a good location.
