The studio is small, but nicely appointed for a single traveler. The building is secure, and there's a small elevator. The bed is a pull-out couch bed. There's a lounge chair, a small desk and chair for working. The Kitchen has a small refrigerator, a sink, two burner induction range, a microwave, toaster, pod coffee machine, and a hot water kettle. There is a washing machine in the unit which spin-dries laundry. The wi-fi is good. There's a window facing a quiet courtyard and a view over the rooftops.
The neighborhood is more working-class and not as touristy, but there's plenty of local eateries around, and is close to both Le Bassin de la Villette and Parc des Buttes-Chaumont. It is immediately next door to a small grocery that is quite convenient. Located within walking distance to stations on the Metro 2 and Metro 5 lines.
It's an old Parisian building and isn't 100% quiet. During the day, you can hear life in the building. There was an incident while I was there with the water service being turned off, but Davediuc was very communicative about the issue and came down to help fix it. An excellent host.
I would stay there again next time I was in Paris.
