My wife and I stayed here for 6 days and from check in to check out it was smooth and easy.
Location: Walkable to the Louvre, Jewish quarter, and Marais areas; very close to 3 metro stops; many Chinese restaurants and local bars nearby; the apartment building is quiet and safe.
Check-in: The host was proactive in getting in touch with us a few days prior and allowed us to check in before noon; the cleaning lady/helper Tina greeted us in a very friendly fashion in English and answered all of our questions; the host has prepared vital info about the apartment and other tips that were emailed to us beforehand.
Space: Very compact but has everything one needs; on the ground floor where your immediate neighbors surrounding the small courtyard are an accounting office and a restaurant storage room—only saw the latter once during our stay; washer/dryer and Nespresso machine were especially useful; the sofa bed is what it is—not that comfortable but okay for a few nights; bathroom is small and doesn’t offer much privacy (just a sliding door); I cannot imagine more than 2 people staying here or if you aren’t really familiar and comfortable with each other.
Overall, a great place to stay and very smooth experience with the host. Merci!
