We were in “the app”with 2 adults and 2 kids (15 and 16 years old). Be aware: there is simply no room for 4 incl. luggage, the appartment is max. 18 m2 in total.
There are no curtains (meaning no privacy and a view of the waste containers of the entire flat) and there is no airco or wifi.
If you are a somewhat fuller person, you will have serious trouble showering because the shower is extremely small. And the toilet grinds, so makes a lot of noise.
To end on a positive note: The location is good. 10 min walk from the Arc and many restaurants and grocery shops in the street. And the host is responding om communication very quick.
