Cabaña junto al río Noosa en un entorno de arbustos australianos

The guest booking the cottage stayed in the cottage only for a few days of her 6 week booking. For the bulk of the booking the cottage was occupied just by her 19 year old son on his own. Guests in the adjacent house noted that the cottage windows were always fogged up, with water running down the glass. Our cleaners also reported same. The result of lack of ventilation over a period of weeks was a build up of mould. The obvious cause of the problem is leaving the aircon on a very cold setting 24/7. The boy's mother claims he did not use the aircon "because he did not know how". However she was not staying in the cottage. There was no mould when her son checked in and prior guests have not reported any mould. Remediation (professional cleaning of walls, ceiling, curtaind and blinds) has cost us over $2000. This is not a situation that could have arisen due to acceptable use of the cottage..Hence we cannot recommend either the (absent) booker, or the actual guest who stayed.
