We have stayed with Justin for 4 nights.
The apartment is easy to find and very close to the Metro station, Goncourt of line 11 (within 3 minutes walking distance).
The neighborhood is lively, full of restaurants that open till late, also with supermarkets and pharmacies so for sure you will be well taken care of your needs.
The apartment is even better than the pictures and descriptions Justin has shown. Very spacious, stylish, extremely clean. You will not be disappointed if you are attracted by the artsy vibe of the photos like I did.
Justin, the host, is very friendly. Often with swift and helpful response.
All in all, we enjoyed our stay a lot. If you are looking for an apartment slightly further from central Paris (Region 1, 2, 3, 4, 5, 6) and would like to experience the local vibe. You should definitely book Justin's listing.
