I had a great time at Mathilde and Nicolas' house. It was exactly what I was looking for: an affordable apartment, with multiple rooms in a safe neighborhood. The interior was completely my taste and made me feel at home. The kitchen had everything I needed to cook. I could do my laundry. There was a table where I could eat, but also do my work. The bed was super comfy. The neighbors were really nice to me. I loved the private courtyard where I could sometimes eat outside. Parc des Buttes Chaumont was only 5 minutes walking away. Everyday I would go there for a run.The neighborhood was quiet and peaceful. There were lots of nice local shops to buy food and 2 nice cafes to drink (or eat) something right around the corner.
The communication was always good. They are very friendly. I felt free to ask questions if I had any.
It is a little far from the city center, but this was never a problem for me. I chose this location, because it was close to the parc and Belleville. Both on walking distance. Even when I went out in the 11th, I always managed to get home easily by metro or by renting a bike.
Of course this is somebody's home. There were a lot of personal touches and belongings and you can tell that somebody lives a life in here. I personally like this, but if you expect a minimalistic hotel room, then this is maybe not for you.
I had a great time. Would definitely recommend this apartment if you want to have a more personal experience where you feel as if you live in Paris.
