This is basically a small hotel. I didn't have much interaction with the host because of that but I did like the fact that I had my privacy.
About the room and the place itself: it was spacious (in french standards), the bathroom was private and clean with nice hot water which was very good. The bed was big and the room had a good amount of storage space for clothes and things and enough plugs. There was also a tea maker which was a blessing. But the floor of the room was very unclean and because of that you could find dust and lint everywhere, specially on the linens which is not very nice.
But the main issue I had was with the location, though I know that this has nothing to do with my host. The hotel is quite close to the metro line but the neighborhood is quite unsafe, specially is you are a solo woman traveler like me then it can be very dangerous in the night, and I don't mean really late in the night. I was coming back home even at 8 PM and I felt unsafe. So despite the fact that it was a comfortable stay in the room, I would try to stay in other neighborhoods of Paris next time.
