Hello,
First at all, I found the address easy and very close to the railway station Gare du Nord, so I got myself walking over there in only 15 minutes.
Actually, the localization is very smart, from here you can go to anywhere by metro and buses as well by foot, if you like walking around. Near to Louvre Museum, Montmartre, and many other amenities.
Other important think, was the kind attention and care dispensed by the owner. He explained me any detail about the studio, how to use different house equipment like: TV, washing machine, kitchen, bathroom and so on. Here, it is absolutely necessary to add that the room was pretty clean, tide, every thing just in its proper place, making my stay very pleasant and comfortable.
