Great proximity to the Guy Moquet Metro station (5 minute walk or so). We did not spend much time at the flat rather than to sleep, but wish we could have... just a beautiful kitchen and common area.
It was only my nephew and I so we had more than enough room, and I would say that it would be more than comfortable for a family of 4, a group of 4 Adults would be pushing it a little. I would say 3 Adults would be comfortable.
