Hi
I work all day, so I state that my check in is after 7Pm. On weekends I am flexible,but there is no way to put that on the website.
I do not accept instant booking.
So when I receive a request, I ALWAYS ask the guest what time they are arriving, and I point out that check in is after 7pm, and ask if that would be a problem.
I work in central London, so they can meet them there, I keep their suitcases in my office, if that is an option.
The point is that I keep a recorded interaction about chek in time before accepting the booking.
