Hi Melissa,
Just a couple of suggestions.
No amenities like shampoo and conditioner we always supply.
Nespresso machine for good coffee - we supply in our holiday home and no-one abuses it but we always get great comments.
Not that we used them but charging for extra sheets is an issue for us.
Also why the late checkin and early check out? With a hotel that is constantly full can understand. We have our holiday home on both AirBNB and booking.com and allow a 10am checkin and 12noon check out as we block out the day before and day after so there is no rush with cleaning.
Understand each to his own and only suggestions.
Cheers
Russell
