My husband and I happened on Laurent & Isabelle's place after our first Airbnb fell through. After one week of walking up five floors, we both agreed it was kismet: that we landed in the perfect place for us.
The flat is located perfectly on a tiny square you might not expect much from if you arrive in the late morning/early afternoon, but it livens up at night in a unique neighborhoody way that's impossible for me to put into words. We always felt like we were returning home after a day of wandering the city, and that feeling started after one night.
Laurent and Isabelle were attentive hosts. And they give great restaurant advice!
My husband and I have already decided that when we return to Paris we're staying with Laurent & Isabelle again!
