Guest requested ful refund which I refused:1. Guest presented one (1) bed bug to us on day of departure. Called-on expert assured us that the place was not infested with bed bugs. No trace of any bed bugs could be found. This notwithstanding we treated the place anyway for a preemptive measure. I refute the notion a) that the place was bed bug ridden, b) that, if so, it was our fault.2. Guest was instructed how to use the A/C in order not to have it iced over and stalled. She proved to be resistant to guidance. A/C technician could find no fault with the A/C other than it being wrongly used. After it thawed it work just fine.3. Pool is serviced once a week. If there was insulation, screening, and trash inside it was put there by guest.4. Guest evidently enjoyed her stay to the very last day -- since she did not complain before departure day. Only after being refused a refund her experience became "nightmarish".
