We were a family of five, staying only for 2 nights, in this lovely apartment and overall we had a pleasant stay.
If you're a light sleeper, the back bedroom gets flooded with light when turned on outside by passing residents in the night (the bedroom has a section of glass bricks in the wall to allow for more daylight). It's located in the 3rd, the beautiful Marais, with fantastic supermarket, coffee shop and restaurant options. Many thanks for a lovely stay.
