Don't hesitate to book Mélodie's apartment. It has everything you could want for a visit to Paris. Mélodie is the perfect host in every way. She is responsive, helpful and her communication with you is excellent. The apartment itself could not be more charming, comfortable and well designed. It is full of natural light and also spotlessly clean and well maintained.
The location is very central and you can walk everywhere. It is in the center of things but off a lovely interior courtyard so it is pin drop quiet. There is a very typical, very Parisian view into the courtyard from the many windows. You won't be disappointed.
There is a Metro stop right at the end of the street which is very convenient.
