My overall feedback about the apartment is positive.
Sylvain was a responsive and helpful communicator. Smooth check in and check out (very flexible).
The apartment is quite big and sufficiently cozy and confortable, as described and pictured on Airbnb website. It is a fourth-floor walk up apartment (so no elevator), with quite modern style furniture, located in the X arrondissement (not very central but 50mt from subway line 4, 10 minutes walk to Grands Boulevards).
The only aspect we really suggest to improve is about cleaning: so much dust, stained and quite unpleasant toilet and kitchen equipment not very clean.
Apart from these aspects related to cleaning, however, we recommend the apartment ;)
