This is an incredible apartment and in an excellent location. You can get basically everywhere from the nearby metro and there are 1000' of restaurants and bars nearby.
You can also get here by 1 train from CDG. The apartment is really clean and Vincent is an excellent host. He was communicative and answered any questions we had and also let us check in early and when our plane was going to be delayed he said we could stay another night if needed.
I will mention that if you are a light sleeper then you should bring some earbuds as the street outside is noisy and this is not due to the windows or anything in the apartment it just is what it is.
