Pros:
Location: 5/5
Convenient location close to many cafes, eateries, art boutiques and minutes away from Place des Vosges.
Cons:
a) Cleanliness: 2/5 Value: 1/5 Accuracy: 1/5 Communication: 1/5

Our host, Susanne, failed to disclose to us of onsite ongoing construction works which we only discovered on our day of arrival. Immediately, we reached out to her on the issue and her reply was that while she was aware the renovation works was scheduled to be carried out in the next couple of weeks, she wasn't expecting it to coincide with the period of our stay. As the discomfort and inconvenience from the noise (contractors were gutting out the walls) and dust made the place inhabitable especially since we were travelling with our kids, we vacated the premises once we found alternative accommodation (which was fortuitous given that it is tourism peak in Paris currently).

Other observations:
Apartment was relatively clean (except for the dust) but appeared more worn and tired than that depicted in pictures. There is also quite a bit of street noise as both bedrooms' windows face a major street.
b) Check-in: 1/5
Host provided an incorrect pin code for the 1st main door and we were stranded outside of the building for a while on day of check-in until a kindly resident informed us that the pin code was wrong.
Overall:
We had an extremely poor experience with this accommodation due to the reasons stated above. The issue was a dampener to our trip and disrupted our travel schedule quite a bit as we had spent considerable amount of time liaising with our host on the problems as well as sourcing for alternative accommodation.
