Melissa apartment is very cozy, it works for a friend and myself and it's located in a lively, high tourist area. 1-2 minutes walk from notre Dame, really close to the metro. 1 metro ride from CDG. Check in was very easy. We arrived before check in and she was nice to let us leave our luggages. Side note: it's upstairs, narrow staircase, and the walls are thin. She was a great host!
