Sébastien's place was located perfectly for everything I wanted to see in Paris. He is also very friendly and helped take care of my luggage when I arrived early. His place is on the smaller side, but is furnished well and well stocked. It had everything I needed for my stay. One thing to keep in mind is that there is a restaurant kitchen underneath the apartment, so light sleepers should bring earplugs. This didn't bother me though.
