I stayed there for 10 days. Hannah's place is just perfect for staying in Paris. The location is in the center of Marais and super convenient for everything.
There are a lot of restaurants, cafes and supermarkets in the area so you don't find any inconvenience if you don't bring anything. Picasso museum and Pompidou Center are also walkable distance.
The apartment is very clean and spacious. Co host Anaelle was very helpful. I stayed in Paris more than 8 times but this place was the place for my experience so far.
