Hi
@Victor12 I'm not sure I understand your question - you can either block off a day, or not.... I handle it in the following way.
Checkout is 11 am - checkin is 5 pm (a bit later than most). That gives me 6 hours to do the cleaning (I actually have someone else come in and do it, so that window is large enough to do what usually takes about 2 hours). You could extend it, too, make your checkout 10 am, and checkin 6 pm - that gives you 8 hours. You will get a lot of requests to checkin early - I usually agree to it if the unit is empty the previous night.
Setting aside a whole day seemed to be too much to lose, especially since many of my bookings are 2-3 nights - I would lose about 8-10 days a month!
Hope that helps -
Susie
