While Clemence is a nice person, I strongly suggest you read all of the reviews before booking to avoid the same uncomfortable situation that I was in.
Clemence only has one key for the apartment, guests must coordinate and are limited on their ability to come and go freely. If you come back late, you will have to wake her up to be let back in. While there were other minor issues, this was enough for me to ask to check out early.
Although a majority of the reviews are positive, re-reading all the reviews shows that there are quite a few others who also felt uncomfortable given the situation. It's also confusing as there seem to be multiple listings under different names, but the descriptions in the reviews all indicate it is the same place.
The description touches on it, but the room is her room and she sleeps in the (tiny) kitchen while guests are there. All of her things are in the room, and she needed to come in to grab something on at least one occasion. The kitchen is very small, and between her bed, her things in there, the closed door, and the dirty dishes, I did not feel comfortable using the kitchen. As a few other reviews have noted, the shower has mold in it and overall the cleanliness was not that great. There was a persistent odor in the apartment that I could not figure out.
After asking to leave early, I had an uncomfortable conversation with Clemence about how she said I was expecting a hotel instead of Airbnb and she was very bothered that I had not been talking to her and asked to leave early. She seemed like a very nice person at first and I wanted to leave a positive review, but overall this was not a comfortable experience for me.
