The apartment was well located and Maguy's friend was really nice with us since we got there. They allowed us to let our luggage in the house while we toured the city before departing, and also left us the keys a day more.
Breakfast was good. The place is also extremely silent at any time of the day and night, so it is perfect to relax after a day of museums and stuff.
Placement is perfect, near to the public transportation and close to Velib' stations!
Maguy and her friend are really discreet and polite: if you ask for something, they're there for you. If you prefer to mind your own business, nobody will ever disturb you.
