Juliette is a very kind and welcoming woman. However be aware that she finds cleanliness very important. The apartment is therefore very clean but you are expected to keep your room tidy at all times. Eating and drinking is not allowed in your room only in the kitchen. Juliette gives you a lot of tips on how to get where you want to go quickly and what spots in Paris you shouldn't miss out on.
We came here for a concert and on that day she allowed us to shower late even though she normally wouldn't have wanted us to, because it would wake her neighbor. That was kind as well. She also offered us small things like tea and coffee for free.
Overall we had a pleasant stay and a great time in Paris.
