calculation for beds and bathrooms?

the market i am looking at i s a pretty condensed area with people realize that it will be a space that has a lot of beds.

my question:

what is the sqfeet or sqmeters ratio to the amount of beds is best to put in a hostel. If i am looking at a 500sqm or 5000sqft place, how many do i calculate i can fit in there? i understand that it all depends on the building outline but a typical answer will be great.

how many bathrooms do i put in per bed? is it 10 beds per shower?

thank you very much in advance!!!!;)
