There are so many choices of arrondissements and places to stay in Paris. I am glad I chose to stay in Mathilde's apartment. It is exactly as pictured, only it is a little bigger than it looks in the pictures. There is a lot of light, and the shower is GREAT. She leaves big thick towels (better than the hotel I stayed in after I left Mathilde's). The bed is comfortable and big enough for 2. Although in a very busy neighborhood, the street is off to the side and very quiet. This was perfect for my friend and me. And Mathilde did not charge any extra for my daughter to stay with us for two nights.
You can walk everywhere (and we did !) and there are lots of cafes, patisseries, stores, etc. all within a block.
Mathilde was a great host - she was 100% responsive to my many questions before I left. When I arrived, she offered to help me if I needed someone fluent in French to help find my friend who was 'lost' somewhere in Brittany (I found her). The 'check in' was perfect - she met me promptly at the apartment as planned, and gave me all her contact info if I needed anything. The departure was just as easy.
I recommend Mathilde's apartment to anyone who is looking for a lovely and comfortable place to stay in Paris, and who will be greeted by a kind and thoughtful hostess.
