I can see your listing - it looks very nice.
I was a bit confused by the sleeping arrangements. I only see a double bed, which seems to be in the living room. I cannot see any photos of a single bed.
It's best to be very clear what the living and sleeping arrangements are otherwise some guests can have the wrong idea and give a bad review.
Also - in your house rules, I would state that only a maximum of 3 people can stay - as at the moment you say, No Charge for Extra Guests.
Good luck
