As others have mentioned the apartment is in a great location to access all main tourist sites in Paris and about 10/15 min walk to main train station to connect you with eurostar/airport
Myself and my daughter stayed for the weekend and again need to say it was a bit noisy, more so on the Friday night then Saturday but can't talk about non weekend nights.
The shower drain also needs looking at, it was a bit annoying having to keep stopping the shower to prevent the water flooding out.
However despite those 2 little things it was ideal for our needs and wouldn't hesitate staying again or recommending.
Thanks Ben
