Sylvia's studio is just as pictured and described, albeit with some changes to the kitchen supplies and the dining table. The apartment is on the 7th floor of the "C" section of the building, meaning it's a bit of a walk to and from the building door. The area is about a 40 min walk to the center of Paris and 10 min to the Sacre Coeur for a beautiful view of the city.
Sylvia is a fantastic host. She's very warm and although she speaks little English, she makes her instructions fairly clear. It was lucky I knew some French numbers and phrases, but if you don't, I recommend having a translator app handy.
My friend's and my issues were that the bed was uncomfortable (other reviews say the same) and in December, the radiators were a little weak and the apartment was cold.
