We absolutely loved our stay in Paris. The apartment had everything we needed and was more spacious then it looks in the pictures.
It was extremely clean and comfortable for a family of four.
Le Marais is a beautiful location and it was easy to access all the sites of Paris using either the Metro (Saint Paul station is a 5 minute walk) or the buses which stopped around the corner.
Lots of cafes, shops and supermarkets within walking distance, including BHV. We could easily walk to Notre Dame as well.
The host was very responsive and the unit is as described and we highly recommend it.
