For stays of 4+ nights you get Trash and Towel service on Day 4. During T&T service, all of the bath towels are replaced, trash is emptied, and some consumables are replaced (dishsoap, laundry soap if w/d in room). For the T&T day, housekeeping does not make beds, run the vaccuum or do anything else other than the items previously listed. They'll be in-and-out in about 3 minutes.
For stays of 8+ nights you get a full cleaning on Day 4 and T&T service on Day 8.
The scheduled days can be changed at check-in if you wish. If you want additional services, you must pay for them. The cost varies depending upon the size of the villa.

Studio full cleaning: $25 per day
