Zazie's place is fantastic! It's extremely well-located right in the heart of Paris, and the metro is only a short walk away. The whole house, as well as the room you'll be staying in, is very well decorated. A lot of unique personal touches that make it charming and Parisian.
Zazie herself is very kind and hospitable. She's very knowledgeable of the area and more than willing to provide any local tips you may have on your trip. And of course, if you wish, she's also willing to provide breakfast every morning.
I would definitely recommend this place for anyone looking for a more authentic Parisian experience with a friendly and conversant host.
