We have stayed in this apartment with two families and our mother. The apartment is well accommodated and has everything you need to really live in Paris. It is quiet, spacious and clean. The showers are a big plus too. They are of a good size and the water pressure is just right.
Because of the location in the building you will not hear any noise from the street.
The hosts are caring and willing to help you with anything you need.
We will definitely stay here, or in any of their other apartments, next time we visit Paris.
