For a city apartment the noise level is very good. We’re light sleepers and didn’t have trouble falling asleep.
It’s a bit of a walk to get to the train and metro station, but very doable. Lots of little shops and restaurants along the way, so a nice stroll at the end of the day.
There is a TV in the apartment but doesn’t have any channels so you’ll-need to take something with if you want a quiet night in.
Overall we enjoyed our stay, and I think it’s very good value for Paris!
