The apartment itself was beautiful, clean, and just as pictured.
My biggest concern was the location of the apartment building. Yes, there were prostitutes on the street but they were never a problem for my family. Our problem was the neighborhood. We were a large group of 7 Asian tourists and we did not feel safe walking around. At one point we were followed onto Rue Blondel by a man who seemed like he targeted us. We definitely felt targeted as a group because we are Asian and that was something we were concerned about with Paris in general. But it was alarming that we did not feel safe walking back to the apartment. This is something that isn't Yohann's fault but just something to keep in mind when booking this place.
That being said, the apartment itself was wonderfully equipped and great for such a large group. Yohann and Morgane were communicative and helpful with check in and all information we needed. One issue we did have was the wifi did not reach the bedroom with two beds but that was not a huge problem.
