Jean-Luc has a lovely, quaint apartment in the bustling 11th part of the city. It's on a quiet side street, but just steps away from trendy restaurants and shopping. It's super easy to walk to Republique and near several metro stops.
I'm a very tall guy and found the bed very comfortable, also the kitchen is equipped with a full refrigerator, washer/dryer and TV that allows access to online viewing.
There is however no living room, which if you're out enjoying Paris, you won't need one, but there is a small table with 2 chairs for eating meals. If you're looking to sit on a sofa or hang in the apartment for long times, this may not be ideal for you. But for a single person or romantic couple it's just perfect.
Jean-Luc was super responsive and a good communicator. I sent him a reply that somehow didn't go through and he was very patient and understanding with me even so.
