Four of us (women) stayed in the apartment for ten nights; it was spotless and the security very tight. Olga let us check in early which was wonderful. The beds had been pushed together so we each had a large bed, the linens were crisp and extra blankets available. (There were no extra sheets or towels as noted by a previous guest.) The apartment was warm with central heating and the shower/bath had plenty of hot water. There are two sets of windows and thick curtains so quiet and dark.
The location is safe and close to many restaurants, metro stations and Rue des Martyrs.
We highly recommend the apartment and would certainly stay here again.
