How would you equip 3 bedrooms for sleeping?

[Rachel Hughes]

How would you furnish 3 bedrooms for sleeping? I am purchasing a 3 bedroom home with an ADU. My husband and I will be living in the ADU and using the main house as an STR.

The property is in a residential area and not really walk able to any restaurants/attractions. I am not sure what type of guest we will attract but I have a feeling it will be families. Looking at the numbers, being able to sleep 8-10 would be advantageous. 

Here is what I am thinking...

Bedroom 1: King bed

Bedroom 2: Queen bed

Bedroom 3: Two twin bunk beds? Two full beds? two twin XL beds?

Living room: Daybed with trundle (doubles as a couch)? Queen sleeper sofa?

I am worried that bunk beds are too child-ish and might turn off larger groups of adults. However, I'd rather cater to families than large groups of adults that might have bad intentions... In your experience, do families with lots of kids use Airbnb? Is it better to keep a more mature look?

Any insights from hosts would be appreciated!
