First, there is free phone service (land line) in the house so the property phone could have been used to call the property manager with any issue. Unless you have Verizon service on a cell phone, you won't get reception.
Next, the hot water was promptly addressed the next day with the day of no hot water credited back to the customer.
We have landscaping service come out every two weeks. As far as her other issues with lady bugs or a wasp nest on the porch, had we known about them, we could have addressed it at the time. If there is a two week gap between guests after the house is clean, some issues could arise. We always pride ourselves on addressing any issue to make sure our guests have a comfortable and enjoyable stay.
The problem is finding out issues after the fact that could have been addressed, and then being black mailed for a free stay or a huge refund after a guest leaves or a bad review will be written is not fair.
