The complete white one: where Ana is standing which look in a more open space. There is a rug. We cannot see a lock but its pbviously behidn Ana and the camera could be selfie mode.. not sure. but the door is in a corner and if youre standing behind it (on the other side) and enter this room you use your righthand and push the door open you see towards the open area. On the floor you see a thin long layer same color as the floor (cant think of a word in english), this blocks light or anything to be slided under the door . The again, theres a rug... wpuld you put one in the entrance? Or by the WC?

other door has the dark panels on top, opens towards the corridor and if you come from the other side you see a wall right away on your right, not the corridor that takes you to living room. Below the door theres no bump on the floor blocking like the other door.. its more open. And with those dark squares which to me it looks like it can show if the other room has lights on or off, i doubt a main entrance would have this type of door for privacy you dont want everyone to know if your light ms are on. I would think thats to see if theres someone in the WC. We do see a lock. No rug. Would a main entrance in thistype of apartment be in the smallest area of the place or in the open space withh a rug ?
it would make more sense for the WC to be in front or close to what was meant to be the a bedroom which Ana uses as a closet.
