The apartment is very nice. it has been recently refurbished, so mostly everything looks new or almost new. The balcony is large, for Paris standards, and everything was very, very clean. Overall, the unit is well above the average quality in Paris, both in terms of finishing and size. I would definitively recommend this apartment, except for a few details that I mention below.
There are a few inconvenient details. The most important is that the "queen" bed is tow twin beds put together. They tend to separate when one is sleeping. Plus, the mattress is not optimal. For short stays it could be fine, for longer stays it could be a problem.
Other details, there is no Iron or a rack to hang the clothes after laundry.
