The apartment was just like described, it was a little bit small for my wife and our two teens, but at the same time we did not went to Paris to stay in the apartment. The place was clean and we had what we needed for breakfast and diner.
We did not meet Laurent but the instructions he gave me were perfect and he was checking on us and giving us tips (restaurants and other) every day. When I asked questions I got quick reply and communication was good.
The only thing that we would have liked is air conditioning. It was really hot in Paris when we were there and without AC in the apartment it was hot and humid also which made our nights uncomfortable.
Great place overall, I recommend.
