We have five people and the space is perfect for a group of people like us. It's at 18th area five mins walk from metro 2, three min from metro 12. Our friend told us it's a dangerous area, but to be honest we don't feel any threat at all.
It took us 40min by metro to Eiffel Tower. And around one hour away from airport ORY.
Supermarket bar, restaurant are very close by as well. Our helper miss S is funny and helpful too. Had a wonderful time there.
