@Huma0 That sounds like an interesting option.
Here in US, I use my Social Security number for such things. Do not know the equivalent in the UK. The IRS has what they call a Taxpayer ID number for those times you do not want to give out your SS #. Maybe there is something similar for you? I use the title of the listing, since we only have one rental, "Aspen Creek Bunkhouse". Here it is cheap to file a DBA for what ever name. I would think you could just put your own name, too. We have insurance on our AirBnB rental under our names.
At the college I used to work for, one host had 4 boys, 2 rooms with bunk beds. They were 16 - 17 years old, I am sure you would not care to have that many boys in your nice place! But, he was enjoying the boys, and the extra cash 😉 They did cook evening meals, and also gave the boys a ride to school. But, he worked as a tutor for the college, a double dipper.
I really like the night nurse we have rented to twice, now. Works 12 hour shift all night, sleeps all day. Does not even cook. Eats a lot of raw veggies. I would like more tenants like him! I have considered giving our card to the hospital he works for.
