Jean-Luc was an amazing host! I was traveling alone in Paris for the first time and my sim card (data/service) wasn't working. There was a bit of traffic, but I didn't have the means to let him know I'd be late. He waited patiently and was super welcoming when I had reached the listing. He let me know the best transportation routes with the current Paris metro situation as well.
If you are worried about not having your own personal space because it is a shared space, Jean-Luc is very mindful and keeps to himself. He is also approachable to make sure that you can ask for things (recs, wifi, making room in the fridge, etc).
Would recommend the space! :)
