Need to change listing from 5 bedroom to 4 bedroomm

Hey guys

Due to new council regulations we have had to alter our sleeping and bedroom configuration for our property. We can now sleep 8 instead of 10 people and have 4 bedrooms instead of 5. Our bedrooms consist of the following bedding configuration. Bed 1, 1 queen bed Bed 2, 2 single beds Bed 3, 1 queen bed Bed 4, 1 queen bed

How can i change my listing heading and remove one of the bedrooms.
