Pretty horrendous. Main problem was it was an extremely hot week while we were there. The building was being renderd/painted during our stay. There was scaffold everywhere plus screening. You needed to open the windows during the day but did not like sharing the world with the workers. The flat should not have been rented during these works.
On the map it appears to be on the corner of small streets. They must have been the busiest in Paris. At night, you had to open window or the heat would kill you. So we opened the windows but did not sleep due to the racket.
Pretty bad; never again.
