This place is okay for a few days for a couple or one person. It is conveniently located close to two lines of the metro, which makes travelling around Paris very easy and accessible. The place has a kitchen that is convenient, hot water for showering and a good sofa for sleeping.
A downside is that it is tiny, so when you open the sofa to be a bed there is not any space left in this one room. That means that you cannot use the table and chairs inside at the same time. As we visited in October, it was too cold to stay in the patio so we did not use it, although it looked nice. Since the room is on the ground floor, you can hear everyone that comes into the building and goes out, and your neighbors as well. That and the small size were the main downsides. Also, the first night there were a few mosquitos which can easily be solved with a mosquito net. There is no Wi-Fi as indicated on the offer.
A positive thing was the flawless communication with the host, Malika, and the check-in procedure. We got the key from a key safe in the nearby supermarket which was super easy and fast and managed to get in the room without a problem. Malika was very nice as was the lady who cleans.
Overall, it is convenient for a short stay in Paris.
