First off, let me stop the rumors; the air conditioning was exceptional. We were there on the hottest week of the year and the A/C kept up perfectly. It is part of the building A/C so it is also super silent.
As for everything else, the unit was super clean, the bed was great. Shower was amazing. I think they have recently renovated because it seemed brand new. Paul is onsite most of the time so you can’t be more responsive. The place is in the Marais, so it is already in a safe and quiet neighborhood, but to add to that, the window opens to a private courtyard so it is very quiet.
Also, it is a very short walk to both the M1 (the Metro line that takes you to all the attractions) and the M8.
I strongly suggest you stay here.
