Housekeeping is also not exactly "once a week". If you are staying eight nights or less, on the 4th day you will get "Trash & Towel". This involves emptying the trash (there are easily accesible bins if you want to throw things out yourself), replacing the bathroom linens, facial tissue, paper towels & toilet paper (paper good extras are available if necessary at any time), replenishing coffee set-up, dishwashing liquid, dishwashing detergent, sponges & laundry detergent.
If you stay more than 8 nights, on the 4th day you will get a complete cleaning of the unit, on the 8th day you will get the Trash & Towel and this will repeat every 4 days until you check-out.
