Very responsive, we booked this place two hours before due to a problem with a scam host in Paris, with my wife and our two young kids. The place is halfway between a hotel room and a private apartment. It's a loft with a shared kitchen (with two other rooms). All is very clean, you cannot beat the location in the quartier latin. I would definitely recommend the place to a couple or family. There's also a playroom one level below that we didn't use.
Although it's advertised as a full apartment, I don't consider this as false claim given the explicitly written description on the photo. We will likely come back.
