I had a great stay at Brice’s studio. Everything was very clean and orderly. Towels and sheets were provided, and the room's music theme adds character to the place. In contrast to some of the comments below, there actually was a microwave present during my stay and the electric stove, too, is better than one would infer from earlier comments. The bathroom too is perfect and very clean (though the entrance to the shower is a little narrow — an average beer belly wouldn’t pass through, I suspect). As for the location, the studio is strategically located near Gare du Nord and various metro stops, and based in a predominantly working class neighbourhood where people from various backgrounds — French, Caribbean, African, Maghrebian, Central Asian, as well East Asian— blend well and where you will have no difficulty finding decently priced restaurants and shops. Finally, be advised that the studio is located on the top (6th) floor and that it gets quite warm inside in Summer. Plus, ongoing renovations —I am writing July 2017— and scaffolding in front of your window might keep you from opening the window at night.
Will consider coming back in the future - thanks for having me Brice.
