Firstly, the location is super great, walking distance to the metro (subway, underground), and there are lots of designer fashion store and amazing restaurant in that neighborhood. If you wanna truly Paris life, this location is what you find, you can barely see the travel people, but it only takes 15 minutes to Bastille and Pompidou museum.
Secondly, inside the apartment, the design is quite modern and has everything you need.
William is a kind man who would help the people.
If I go back the Paris, that would be my first choice!
