Great location, clean. Walking up the stairs is a good exercise, so plan your day so not to go back and forth . Very clean, has all the cooking ingredients, so I do not have to buy basic like sugar, salt, etc...

Good value for the location.
Get Velo Lib near apartment, you can ride the bike around the city
If you rent a car to go outside of paris, rent from Sixt.com ( Porte Maillot), it's walkable from apartment and right near exit to Highway to avoid traffic ( nightmare if you drive in paris).
Overall, great location
