Marie is absolutely super host.
She invited me to her own room on the first day I arrived in Paris.
She opened her red wine for me and told me anything I want to know about Paris.
The room is also great. I believe it is a typical Parisien ou Parisienne style garret room.
You can see the beautiful scenery of Paris from the window.
I loved to see the blowing smoke from the chimneys and the pigeons (or people, sometimes) on the roofs at the dawn and dusk.
You can cook for yourself in the small kitchen.
There are two delicious bakeries near the apartment. You can buy a baguette there, and some foods in supermarkets like local people. These foods are cheap. (Baguette: 1.00 euro, 6 eggs: 1.00 euro, for example)
Thanks for that, I could save a lot of money and could spend other things.
Of course, there are many nice restaurants and cafés in Paris. However, you may want to cook for yourself sometimes if you stay long.
Paris is a wonderful city and you may have great experience in some attractive places like museum, restaurants, café, bookstore, etc...
But, staying this room itself may be one of the most valuable experiences for you.
