We really enjoyed our stay! There are plenty of reasons I’d recommend this place :)
clean and warm, many spaces to store the luggage, sufficient dinnerware(plates, bowls, spoons etc), a size-changeable meal table, comfortable beds(A sofa bed was also very nice. It was big and the mattress in the closet was extremely soft), private space with curtains, central location, close to subway, very safe(safe street and there are many doors with codes when you enter the place), many useful tools(scissors and tape), quick response to guest’s questions
I could see the detailed care of the host who tries her best to make the guests as comfortable as possible.
But there were also a few things you should be careful about. Try to open the door softly since the big mirror is right behind the door. And the heater makes small noise, you might be bothered by this when you go to sleep.
Overall, this would be the best apartment for 4 people you rarely find in Paris with a reasonable price!
