This room is lovely- it's a good size for one or two travelers, with a comfortable bed (plush pillows and comfy/warm blankets), and space for storing clothes and such. The apartment was actually shared with the mom and son (Nicolas's brother), which was totally fine. They were both incredibly kind and helpful if you need help navigating Paris.
For the kitchen- they kindly left me a shelf for any wine or cheese storage.
For laundry- althought I didn't end up using it, they offered me a washer AND dryer, and a dryer isnt common in Paris so that was a nice addition!
For general hospitality- Thibault (Nicolas's brother) is very kind and made sure I had the right outlets so I could charge my laptop, many fresh/clean towels, etc.
Only downside was the noise from construction outside my window- lots of yelling and banging when I tried to sleep in on two days, but if you're going to be up before 8am, you'll be fine. It's also very quiet at night, the shower is great, and the area in general is safe and a super short walk away from the metro. Would return to this Airbnb next time I travel to Paris!
