Marie’s flat is the perfect place to be in Paris. It is perfectly located, just a 3 mins walk from two metro stations and even walking distance of the major touristic attractions. The area is full of restaurants, pubs and shops so you do not have to worry a bit (great and cheap restaurants all around - would recommend Super Bao burgers just around the corner).
It fits 4 very well, very clean and has everything you need.
Mary is a wonderful host, easy to communicate with and very helpful.
The flat is worth every penny. Would love to stay there again.
