Having lived in Paris before, I can say with absolute certainty that even as a resident it is extremely difficult to find a place in a great location, with peace and quiet as well as enough space. Louis's place has that.
Additionally, there is a rarity to deal directly with a person in the city. These days there are too many agents and intermediaries.
For these reasons, as well as cleanliness, excellent local advice, communication and clear instructions... I cannot recommend this place highly enough. If you're a long time Airbnb user and despair for the good old days of the a platform when it was a genuine feeling of community and sharing the environment of a local, then don't wait. Book this now.
