Mathieu was always quick to respond and flexible with the check-in and -out. (There were no guests directly before/after us so we could arrive/depart at our leisure.) The place is very centrally located at Place Pigalle, and the windows are new so all the noise from the boulevard is completely closed when they are closed. The place gets quite stuffy when it's warm outside (there is a small fan in the room though) so be aware of that. Everything is as described and should you need help with something you can count on Mathieu being there for you for sure ;)
