Enjoyed a stay here for four nights. Check in process was painless with lots of information provided in advance. The apartment was very clean and beds firm but comfortable. There are quirks such as random steps but it's a Parisian apartment, so these things are to be expected. The location is amazing with lots on your doorstep and a few minutes walk to Metro/RER stations. Minimal noise from the street. No AC, again as expected, but plenty of fans provided.
The shower definitely needs something to provide foot grip as it was very slippery, and more pillows would be appreciated.
If you are looking a base for Paris with a decent bed and a good shower, it ticks all the boxes and I will definitely consider staying here again.
