This was the first Airbnb for my friend Viktoria and me. We absolutely recommend Mathildes and Jean-Pierres place! It has been very clean, exactly how it is described and really beautiful to stay. It's located just in the city centre so we could walk everywhere and didn't need to use the metro/bus.
Unfortunately we didn't get to know Jean-Pierre but Mathilde has been very friendly and helpful concerning way introductions. We just stayed 2 nights but actually felt home already.
Any time in Paris we would love to stay at their place again.
