If you don't see the letter "H" to the left of each of your units on the main booking calendar, enable the Housekeeping Flag in Settings > Reservation Calendar.
On the far left of the reservation calendar is an "H" for housekeeping status.
- The red square means the unit is dirty.
- The white square means the unit is clean.
The square is a button. Simply click it to change the status of the unit.
When you change the status of the reservation to be checked in, the unit is automatically marked as dirty.
