We are just back from 3 days at Elsa's studio in the 16:eme.
Comfortable and quiet and yet with easy walking to several very good eating places as well as, a bit further, all the buzz around the Trocadero.
The bathroom and shower were particularly appreciated as well the mini-kitchen for that most important coffee first thing.
Some distance to walk to the Metro if you have baggage but not insurmountable.
I would certainly consider going back when in Paris.
