Where are their rooms?!

WHERE ARE THEIR ROOMS?! It is so confusing. I used to think Asad's room was on the top floor because that's where the balcony etc is, but usually they show him coming out of the main floor room near the kitchen. Even Zoya's room seemed to be upstairs first, but now it seems like it might be on the main floor? Najma and Dilshad seem to have rooms upstairs...

I know this is super technical but I feel like it is an inconsistency that really bothers me sometimes.

but then, when Zoya first came to their house, Najma asked her to go to her room upstairs, she even gave her direction, but she ended up in Asad's room 😆.

i am confuse too with this..
