I would highly recommend that you book Arnaud's place. If like us you are visiting Paris for a weekend of sightseeing, this is such an amazing location for getting around, either on the metro (station across the road) or on foot (it is RIGHT next to the river).
The apartment is exactly as described. Clean, light, spacious, everything you could want. What I particularly enjoyed about the space is that it feels like you are in a place that is loved and has a family element. It has a great warmth to it and I loved being there.
As a host, Arnaud is super responsive and makes himself fully available for any help needed. I asked him about how best to get to the apartment from the airport, and he. put me in touch with a taxi service which turned out to be absolutely fantastic. He was also very understanding about our check-out time, and made our trip so much easier than it could have been.
My recommendation is that you book this place. I spent hours searching for accommodation in Paris before settlig on Arnaud's place, and I'm so glad I made this decision.
