It is a wonderful and comfortable flat. We had a best time in Paris with Franck’s helpful instructions on how to get around and all the recommendations on where to visit and to dine (he communicated with us days before we got there).
The place is so nice and quiet, yet, so close to everything - short walking distance to Notredame, Louvre, lot of shops, cafe and restaurants.
And you can easily hop on the metro (close by) to get to other destinations.
Highly recommended, and definitely will stay at Franck’s place when I am back in Paris.
