Great value! The apartment is clean and is in a very quiet, safe area. Soundproofing is great as we didn't hear a single noise from other residents or the outside street. Made for a great sleep every night!
The apartment is spacious and great for families. The kids room is full of toys which our toddler loved playing with. Made it very easy to keep her occupied while we relaxed on vacation.
Location is excellent; staying outside the "touristy" area of Paris makes you really feel like you live in the city. When you want to see the sights however, you have a roughly 10 min walk to a Metro station from which you can get to the center of the city in about 20 mins.
There's a great bakery right across the street and a decent sized supermarket just around the corner. Makes it easy to pick up any groceries or supplies you might need.
JF is a great host and is always very quick to reply to any questions that arise. He was even nice enough to prepare a long detailed list of recommended things for us to do as it was our first time in Paris.
The only thing I'd note is that there is no elevator in the building so you have to take the stairs up 4 floors to get to the apartment. Wasn't an issue for us but is worth noting for anyone with mobility issues.
Overall I'd 100% recommend this location for anyone's Paris vacation!
