All in all there were pros and cons which I will describe:
Cons:
We were traveling with our two little children and the smell of cold smoke in every room was very strong.
The noises from outside were loud until late in the night which made it impossible to open a window. That was bad because of the smelly rooms.
When we arrived, there were no bedsheets for all of us which made us sleep on T Shirts pulled over the pillows on the unmade beds. The next morning we got the beds made by a very friendly cleaning person.
In the bathroom must have been a water damage which caused humidity and water stains all over the wall. That made us feel as well uncomfortable during our four days trip.
Pros:
Friendly and fast response and communication with the agency.
Good Location near Sacre Ceour and Montmartre.
The Interieur was as in the pictures shown.
For a smoking couple it would have been nice despite the fact of the sheets and the water damage but I wouldn't recommend it to any family especially with young children or with a baby as in our case.
