Our family of four (children 8 & 5) stayed in this perfect apartment for five nights in July 2019. We selected it because it was larger than the other apartment listings we found in the neighborhoods we were most interested in and we were pleased with the size and layout. The apartment is located in a cool, secure, quiet, building in an amazing neighborhood - just a block in every direction to cafes, groceries, shopping, parks, metro - it's really perfect and fun for a family.
Thibaut & Alex were very helpful with arrival and check-in and also facilitated us adding nights to our stay. For international travelers I recommend having an international phone plan for your first day so that you can communicate easily with the hosts when you arrive in Paris; they need to meet you to let you in. After that, you can use Wifi in the apartment and other places for your online/communication needs.
Highly recommend and many thanks to Thibaut & Alex!
