M&J apartment is great. We really loved it and recommend it.
It is cozy, warm, bed is super comfy and location is perfect. There is a metro stop right in the front door and Republique stop is 5 min walk. In Republique you can catch several lines which is quite convenient plus on your way you’ll find an amazing Boulangerie 
3 things are my highlights and the reason why we loved it.
1-	If like us, the reason why you choose Airbnb is because you believe in its original philosophy (a way to help locals get an extra income to afford housing high prices), and you look forward to stay in a place with personality this is YOUR PLACE. This is really where M&L live and not state agency business.
2-	The possibility to check out at 17:00. YES!!! Not having to worry about what to do with the luggage if your flight is in the evening and the possibility to fully enjoy your day is a 10 for us.
3-	And finally, but, not less important , the hosts are very very nice. We didn’t have the chance to meet Maxime in person but all the communication with him has been easy and with a sense of humor. He is also flexible and is willing to make your stay as great as possible. His colleague Quentin, who checked us in/out is super friendly as well and always had a smile on his face.
All in all... go chez Maxime et Juli
