Hi @Lisa0.
I just think that if a guest is paying for it, the space is theirs during the stay.
Consider the items in the space and remove personal items, even if this means your wardrobe is fuller than you prefer. Vacuum seal out of season clothes to save space. Remember, they are paying and they are not family.....
Unless you have major health and safety concerns regarding filth, odours, vermin, amenity repairs, or can smell something burning... like bedding from a hair straightener left on! The no fire items can wait till the guest is home, or text message your needs in advance, then wait for a response. As I said, for fire, respond immediately. For any other safety need, like @Letti0, contact the guest, write a rental clause but mostly be very open about the genuine reason for needing access. Curiosity is also not an excuse.
Guests should be offered a lock on their door, and hosts should not be leaving items in the space that they use, even if occasionally. Don’t forget, breaking boundaries and overfamiliarisatiin works both ways, and can work in reverse...
Like @Paul0 and @Sandra0, I must recommend to stay away.
Just my thinking.
