Zazie's place I'd say may be the best BNB in Paris. Firstly, the location is very safe and convenient. It's located right at the corner of a Metro station but we pretty much ride on e-Bike and e-Scooter everyday because it can easily access to nearly most tourist places in Paris. Secondly, Zazie's apartment is pretty and comfortable with many pretty antique houseware and furniture. We were worried about the toilet located outside of our room and may need to share with others. But then we found it's exclusively for us to use and located at the independent hallway. We don't need to worry about using it in the midnight or came back from outside too late or leave early and may bother anyone. Thirdly, Zazie is very kind to us and always try to help and assist us. When our flight was suddenly cancelled due to industrial strike and need to find new transportation to get to our coming destination, she's also trying to make calls and assist us. I'd say you won't be able to find any hostess like this in Paris.
