Laurent's place is an excellent choice for staying in Paris!
The location of his place is excellent, close to a few different subways and weekday/weekend markets. The neighbourhood nearby is alive with shops, cafes, and bars but his apartment is incredibly quiet at night so it's the perfect mix.
The place itself is great. Air conditioning is so helpful on hot days, though opening the windows is breezy and fresh which is fantastic. The place is ideal for two people (love the hammock!), with all the basic amenities that includes the ability to eat in if you want - it's very comfortable with great wifi. It's top floor (5th floor) but for us the stairs were no issue though I wouldn't bring a checkin bag up those stairs.
Laurent's communication level is high, detailed, and very helpful. I definitely recommend his apartment.
