Very good located apartment in Le Marais, 10 min walk from Notre Dame Cathedral, 5 min walk from four metro station (line 3, 4, 11). Not so big but perfect for 3 (not 4) people: bed is not king but queen-size and sofa bed is good for one person (unless you are very intimate with each other). Had problems with wifi, but i didn't tell the host so maybe it would have been fixable. 4th floor with no elevator. Bright and confortable place.
