We just stayed at Caroline's for 5 weeks and everything is as pictured. The apartment is on the 3rd floor (2nd by European standards). She has a very thorough binder with everything listed in the apartment. She has a separate binder with restaurant recommendations.
There is a steep ladder that leads to the bedroom which is quite large for Paris standards. It was a little scary to come down bleary-eyed in the middle of the night to go to the bathroom!
The bed was too hard for us since I have a bad back so we ended up buying an inflatable mattress to put on top for 20 euros at Decathlon.
Caroline wasn't local during our stay so we communicated via Airbnb. She answered the questions I had in a timely manner and I even received a package while there.
The neighbors are all cordial so make sure to say bonjour! Do yourself a favor and try L'Angolo and Alexis around the corner for their bread!
Note that you aren't able to stop in front of the building to unload a car or wait for an Uber as the building in front is a Jewish center and has very tight security 24 hours a day. You can wait for an Uber/taxi or park around the corner.
Overall, we enjoyed all of the amenities and how nicely appointed she has everything. It was a real treat to be in such a great neighborhood, in a lovely apartment for 5 glorious weeks! Thanks for everything, Caroline!
