Both the location and Olivier's responsiveness are 5/5. Such a charming street and unbelievably close to the Eiffel Tower. The metro station is walking distance and you go to Versailles and Notre Dame from there.
I had the unfortunate experience of losing my wallet and passport while in Paris (not my finest moment) and Olivier was very kind and understanding. I was able to extend my rental while getting things sorted. The floors were a bit dirty but he immediately purchased a new vacuum so it shouldn't be an issue going forward. I highly recommend this rental.
