I had a very nice stay. The hosts (Yannick and Fernando) are very nice, accommodating and eager to help if needed. The room is small (this is almost unavoidable in Paris), but the sofa-bed is comfortable. The bathroom is clean and has many amenities. I can not comment on the kitchen since I never cooked.
Finally the location is nice: there is a metro station super close, supermarkets, restaurants and bars.
I recommend it.
