@Jenny1199 My landscaper/mowing guys are the ones who pick up my trash and they charge $10 a pick-up, but they then take it all the way to the dump, a 20-minute drive, so maybe your gal would be happy with an extra $5. I would have them do it every week for the long-term stays.
Other notes on long-term stays:
*I require weekly housekeeping, because with all the good will in the world I know they won't take care of the place the way it needs to be cared for. Even with a discount the price is high enough that I just throw in the housekeeping without adding more than the one-time fee included in the booking.
*I provide paper towels, laundry detergent, dish soap, dishwasher soap. The housekeeper needs those things so better you than a guest who might forget. And I keep them stocked with toilet paper. I buy it by the case anyway.
