The place as stated a studio, but not in stone throw away distance from Eiffel tower;), I mean it's 750m to 900m you have to walk. And I don't think anybody can cover that distance by stone Zhang!.
The host Zhang, has we met once, is really a nice guy to talk and to get advice on Paris, places. And gives us the direction to reach to his flat by the mail by a beautiful step by step procedure.
The metro connections are good with in 300m. If the person you loves to walk it's the suitable place to stay and see the area around this place.
If any one wants to do party, n if they want to cook something everything is available(Utensils).
About the studio, it's really nice located but the problem of the studio(I think ask the studio) is it smells from whatever you do in that little space. And the sliding doors of toilet were really bad, they don't slide good and either they cover area good.
And a suggestion for the big guys :) , you cannot fit in the little space of the lavatory. Since I and my friend were average built and we used go and come back in the same position. ;).
