The room is located on top floor (6th) of a building in the middle of Marais. There is a small elevator that goes to 5th floor, so carrying the luggage up the stylish old building is not a problem.
Directly across the street are few brasserie, a café that offers organic and some gluten-free as well as normal bread and breakfast. Although there are many cafés, bars and restaurants around this block that are heavily visited every night, the room is quiet when you close the window.
Metro station and few bus stops are very close by, so getting around in Paris was very convenient.
The room itself is very small. Opening a large suitcase fills up most of the floor. We visited Paris for a week, purely for tourism, and we spent most of our time outside and came back only to sleep, so it was fine for us.
Unfortunately we could not meet Sébastien in person as he was not in the country, but he was very helpful and attentive. Once we had a problem with the entrance key. I wrote to him on Airbnb message and he replied immediately and helped us out, regardless of the time difference.
Very much recommended for short stay in Paris.
