I totally agree with the previous comment about 'atelier in Montmartre' and the lovely hosts, Carmen & José.
It was my first trip to Paris, also use airbnb. From this trip, I've fell in love with Paris, and I've recommended to my friends using airbnb for their holidays.

When I arrived the atelier, they were not there from their holidays. However they replied directly from my email with full of kindness.
Their flat is incredibly lovely and cozy. The room is big, also exactly same as the photos.
The micro simcard and bike card were super helpful during whole my journey. Also I love the welcome guidebook written by Carmen & José. It is really lovely and filled of many local information :) I could feel their warmheart and kindness enough before my trip.

Fortunately, I could meet them just before my leaving. They were really nice and warm as i expected, even they had got back from their travel.
I definitely wanna visit Paris very soon again, also I would like to stay Carmen & José's place!!
