Excellent position, metro station (two lines) is very close, as well as the station Gare du Nord with easy connections to Paris' two main airports, Orly an CDG. You will be just two streets away from Montmartre and a few more from Pigalle!
The quarter is maybe a bit "lively", but on the contrary the district is very quiet and picturesque.
There is everything you may need in the apartment and Manon is a perfect host, you will get an answer to every question you may have in a very short time.
