I'm overseas at the moment but admittedly I've seen it in the Uk too.
"Apartment for rent, £100 a week for a single £175 a week for a couple"
Aibu to not understand this?
I understand in the case of bills being included etc as gas electric and water would likely be higher/if wifi is included usage will be more so you'd need a higher allowance/unlimited etc. but these are just standard rentals where bills aren't included!
