We recently got back from a 7 night stay at this location. This place was exactly as described. It was clean, spacious, and you can tell the host was super organized. It is a 15-20 minute walk from the popular areas like the Louvre Museum. It is right upstairs from the metro (lines 4, 8, 9) so it is super convenient to get around.
Just like the other reviews mentioned, this place is located on the 4th floor with no elevators. If you have heavy luggage, it is a little bit of work to get it up to the 4th floor. I would also add that there is actually no toilet in the bathroom located in the main bedroom. The toilet is actually located in a separate room in the front the apartment. The other thing I would mention (no fault of the host) is that there are definitely a lot of street walkers right outside of the metro and downstairs from the apartment at night time.
Lastly, we were here for a 7 night stay. The amenities were definitely more bare bone than I am use to for an AirBnb. For example, there was one small bottle of shampoo for us to use during the week and we were also at the market buying things like toilet paper and paper towels.
Overall, we had a great stay here. Eric (the host) even stopped by to say hi and he was super friendly. We would definitely consider staying here again in the future!
