Quentin's place is perfectly described. The studio is a comfortable and convenient place to stay in. At the heart of St. Michel, and a walk away from Notre Dame, St. Germain, and the Latin Quarters, Chez Quentin is a great deal to stay in for your Parisian experience. It is accessible from the airport (~€50 by Über; walking distance from the RER if you prefer train). The community is very safe, and very much alive with restaurants and souvenir and lots of other shops.
Quentin was a great host, and really spent time updating if my stay in Paris was going well. I would love to come back to his place. <3
