Sebastien's apartment is a wonderful apartment! It is spacious, light and airy. It is on the top floor which makes it quieter from other neighbors and the outside street traffic. Very close to two different metro stops which provides three different lines, so it's very easy to get around. There is also a bus stop right outside the apartment. It is close to the Le March des Enfants Rouge which is the center point of amazing restaurants and shops. Just the perfect Parisian experience! For me it was the perfect location. Close to the heart of the Marais district but far enough away that it wasn't overrun with tourists. I miss the neighborhood already!
I did not give Sebastien a perfect score because what he posted on his site regarding sleeping arrangements is not at all how it was when I arrived. He took out the second couch to be place in the other apartment on the same floor which is where he apparently used to live based on previous reviews. He now lives about two hours away from Paris, and it doesn't appear that he has any help in town if there is an emergency in the apartment. So communicating with him was quite difficult.
I specifically chose this apartment because I was going to have two family members visit me while I lived in this apartment for two months. So when I arrived at the apartment I asked him where the second couch was and he told me I should have told him that I was going to have guests. It was a bit odd. Luckily the other apartment was available, so he did allow my second family member sleep there only, but if it wasn't available it would have been much more uncomfortable for us.
So because I feel there is a little bit of misinformation on the website and the fact that it was much more difficult to reach him, I did not give him a perfect score. Overall the apartment was clean but I noticed some things, so I did a whole cleaning for myself because I was staying so long. I was truly living in this apartment as opposed to just visiting for a week and could put with little things. Traveling is all about flexibility, but this was my home for two months.
I would highly recommend anyone to stay there, but if you need more than a bed and a fold out couch, make sure you email Sebastien first to let him know you need it.
