We stay in Paris at least 2 times a year. Have rented a few Airbnb’s and when our favorite place was not available tried James. It is as described but more than that it is a gem. You are in the middle of everything but it is peaceful and quiet.
Open, high ceilings lots of light.
I don’t want to say too much as I want it to be available next time we come :) but suffice it to say you won’t be disappointed.
