10/10 for location -- Property is quiet despite it being in the center of Paris. All major attractions are within easy biking distance. Love the view when you poke your head through from the sunroof window! Some place could use some hooks and shelvings as it was hard to put things in kitchen or bathroom.
Clemence is great. She is responsive and friendly, and very attentive and gets anything that you may need. I love that she was able to work with me to give me later check-out.
I would echo some of the other reviewer's experience in that I found check-in process to be not as convenient and smooth. Clemence did give the don't climb to the roof or "You'll die!" speech. She does asks for a small security deposit (25€), and she makes you sign a contract (a little surprising process for an Abnb) which also mentions you have an electricity quota, 6kW/day, which I'm sympathetic with the electricity crisis and she seemed to had bad guests there before that racked up a big bill.
On check out, she does want to be there to check on the electric meter & take a picture of it and also do an inventory of the place to make sure nothing is missing or broken. If you don't want to stress about your electricity or water usage, this place may not be for you. Otherwise, it's perfect for anyone who is out most of the day visiting Paris and just want a place to take a shower and sleep.
