I didn't have chance to meet Julien in person. But he organised our check in and answered promptly.
Julien's place is sunny, big and have privacy. It's same as posted and located on 5th floor with good view and cool breeze.
I had little difficulty climbing up with suitcase, but it was worth it. In hot summer days, we were ok with wind through the windows and fan.
The house had all necessary items in bedroom, kitchen and bathroom. You may bring towels.
If we go back to Paris, we like to stay in Julien's house again.
