Taoufik was the most dedicated host I've ever met. He would answer any of your questions within the hour and the fact that you could check out till late in the evening made the stay that much more relaxed.
The apartment itself is very clean, and except for a few negligible faults, feels as if it were newly renovated. It is perfectly suited for 2 people, and if you're willing to compromise a little bit on comfort, totally fine for 4 people. The bed-setee is one of the better ones I've slept on. Furthermore, you also have access to an elevator.
Within a 5-minute walk, you can reach the metro station "George V" in the Champs-Élysées. On the way, there's also an inexpensive, but excellent bakery and a supermarket.
All in all, this Airbnb is worth every penny and you should definitely consider it if you want to book a stay in Paris.
