Everything was ok for us, it's a cosy place, we stayed there with 2 kids and they told me : "Mom, we are feeling like home" so that was perfect for me.
The apartment is close to metro, bus, Carrefour, MC Donald's, boulangerie, everything you need. The trains didn't disturbed us very much because we were very tired after visiting Paris all day 😃.
Willy was very helpful and friendly with us. Thank you!
Have a great stay to all!
