I stayed in this apartment for a little more than a month and I would recommend it to anyone planning to visit Paris.
The house has two rooms, a kitchen and a bathroom. David uses one of the rooms and I used the other. The room is very spacy. It was larger than I had expected from the photos. The room is also well equipped. David is very quiet and I could use the bathroom and the kitchen whenever I wanted to.
The house is located very close to the tram station. The tram takes you to different metro lines which makes it easy to move around the city. It is located somewhat in between two metro stations both of which are about 10~15 minutes away by foot. The neighborhood is very quiet and safe. I had no problem getting back home very late at night.
The bathroom is a little old. Nonetheless it is very clean, and David cleans the bathroom very often which was very reassuring.
I had a very comfortable stay for a month in David's apartment. If you are planning to stay in Paris for short or for long, hesitate not.
