A spacious and clean apartment, if you don't mind sleeping some of the guests in the living room.
The kitchen is a bit small, especially the table which can hardly accommodate 2 adults and 3 kids, but it is very well equipped. Wifi worked well, location is good overall - not very far from a Metro station and that one is 2 hops from Etoile, which is a very central station.
The bath is a bit difficult to use without getting the floor wet, which was not very convenient.
Note that the elevator in the building is for 3 adults, and they better be thin. It's also a half floor up the stairs.
