The appartement is perfectly situated a few minutes walk from the metro line 14, very clean, very quiet. The host (Frederic) has been very available when I've been a bit late the first day, and welcomed me warmly. A good amount of documentation is even waiting to be read in multiple languages inside the studio.
There's a small supermarket and everything you can possibly need 5mn walk from the studio and the whole Chinatown just after that, just perfect for my stay, I couldn't expect more. Highly recommended!
