We ( 3 visitors) stayed one week.
Great location to explore Paris! The apartment was cozy and big. You can see the Tour Eiffel from your own window: watch the light show or admire Eiffel in the morning when the city is starrting to wake up - magical!
(+):
*Several metro stations near by
*Nice, hip, and good restaurants just around the corner
*Quiet street and house, nice neighbors
*Easy access to locations either by walk or by metro
*Good shower and other "home" equipments
(-):
*Make sure that you have enough towels, blankets etc. We were missing some and had some issues to get the extras - happy ending however :)
