Renting by room but whole apartment

[Malgorzata30]

Hi there

Is there any way to rent apartment but only charge what guests require.  For example 

2 people - one bedrom (they will be the only one in the apartment!). Rest of bedrooms will be locked. They will be charged $500

Opt2

2 people need 2 bedrooms  - charge $600

So

1 bedroom $500

2 bedrooms  $600

3 bedrooms  $700 etc

Please let me know if this is double.  Thank you! Margaret
