Sebastien is a great host. He was not around when I had to check in because my flight was delayed, however, it did not hinder the speed of check in as he have his friend to check us in. He called me a few hours later just to check if I am doing okay. I forgot to bring my conditioner (I have unmanagable hair without conditioner), so i asked him by message where to find stores that sells them, he replied almost immediately to my message.
I found this place in the last few days before our trip to Paris. The location is excellent, there are fancy restaurants, fast foods, sushi, bars, convenience shops, barber.. almost anything you name it, its there. It is literally 3 mins walk to the Metro.
In short, everything is great, there is double security before entering the house, the area is clean and bright even at night. there is one slight problem though, theres a slight issue with the toilet and bathroom door, also there are no locks on our bedroom door, but everything else is excellent.
