Laurent is an amazing host even though I didn't get to meet him in person. He gave me a phone number of his friend living next door so I could contact him if anything was wrong. Laurent sent many useful information about the neighbourhood what was really helpful during my stay there.
Apartment is close to 2 metro stations from where you can go literally everywhere. There is also a Big Bus station nearby from where you can go to a hop-on-hop-off trip around Paris.
Apartment has everything you need and I highly recommend staying at Laurent's place :)
