The check-in and out process was very simple and well communicated by Pierre. The street where the AirBNB is located is quiet, but the local shops, restaurants and metro station are all within 5 minutes walk.
As for the stay itself, we were blown away. It was better than what we were expecting. There is an old fashioned lift which takes you up to the apartment (French vibes straight away for those arriving). The bed is super comfortable, there is also a kitchen with cooking appliances and fridge and freezer. As the apartment is on the top floor, there is a terrace outside where you can sit and offers a great view of the Eiffel Tower in the distance. If you're staying in Paris for a few days, I'd highly recommend to stay in Pierre's AirBNB
