Florence’ place is great! My husband and I with our two children (age 4/5) stayed at this place for 6 days in mid April. The place served us well. My children slept in the sofa bed, and we used the main bedroom. The bed is comfortable. The place is quiet. Enough place for moving around and unpack luggage. Cooking is easy. Washer and dryer are available, however we found European washer and dryer are very slow. Florence is very kind to provide enough supplies, e.g. laundry detergent, toilet paper, shampoo, dish soap, cooking utensils and oil, salt.... even some food in fridge. The shower water temperature and pressure are both good.
Check in is smooth, check out is easy. The location is great! You can see Gare du Nord from living room. We didn’t mind the stairs either. The steps are not high, so my children managed well. The nearby area is not nice. Lots homeless and sketchy streets. We didn’t go out at night, so didn’t bother us.
In terms of cleanliness of the place, it could be improved. But it’s ok and we didn’t mind. The wall is thin, so you hear everything in upstairs unit. It’s an old building, nothing you can do. Luckily, during our stay, only one night upstairs was noisy.
In general, it’s a very good place to stay in Paris and we are very satisfied. Highly recommend!
