Mehdi lives in this apartment (of course he is gone when you are there) so you use everything he uses in his daily life. Mehdi is a very friendly man, willing to explain everything you want to know. His apartment is clean.
With the RER it took us 10 minutes from Gare du Nord to the station near his house (5 minutes walk). There is also a metrostation nearby.
Mehdi responds very fast on emails. We had a great stay here!
