Dominique was a very helpful host. We checked in earlier, and when we were leaving he kept our luggage after so we could enjoy the day. He gave us all the information necessary and more, with maps and guides and was always available l to answer questions.
The place is beautiful, comfortable and very clean. Has all that's necessary and a beautiful view. We found it perfect for our stay. It's also very conveniently close to the metro and Gare du Nord and L'Est. Supermarkets and restaurants are close by, where you can also find cheap and good food.
Some people might judge the neighborhood by its appearance. As you can read on other comments, no one has ever had problems even though the streets might look different from what we're used to see. People there have a different culture of selling and buying things on the street, like a bazar, which can make them crowded, but no one ever bothered us, not even at night.
Overall, it was a really great experience and we thoroughly recommend the apartment to those of you who want to live just like locals in Paris for some time :).
