Spectacular location and flat. I spent a week in Vincent/Marine's apartment with my mom and sister. The flat is located <5 min from a great metro station and Rue Montorgueil, ~15 min walk to the Louvre and ~20 min to Le Marais and Saint Germain. There are fantastic restaurants walking distance from the apartment and the metro station will get you anywhere else you want to go. Marine was super responsive during check-in and answered any questions we had during our stay. Having 3 bed rooms with my family was also huge and probably prevented some turmoil we would've experienced in a smaller unit. I slept in the "glass room" and with the exception of one night, found the street to be quite and wasn't bothered by the noise. There is a street a block or 2 away that is a bit more seedy, but after walking it once while we were exploring the area, it was easy to avoid. We all agreed we'd stay at the unit again and hope we'll have the chance to in the future.
