Homeowner insurance for Airbnb use case

[Vincent Sun]

Hello! I have a 3bedroom single family house that is used as an Airbnb listing, I had a Safeco homeowner insurance which my agent told me it can cover the short term rental. However recently I reviewed my policy and found the following language in the exclusion section which is quite confusing. I would like to see if anyone could bring more clarity or had similar questions before:

My questions:

-- what does "in part" exactly mean here?
-- If I list **the whole 3Bedroom house** (not the room separately) on Airbnb while I am not living inside, and rent it to the same group of 6 guests (they are friends but not same family). Will this still be considered as "exclusive use as a residence" or will it trigger the exclusion term c. (2) (b) because there are more than two roomers?

Thanks.

Here are the exclusion terms
