As hosts, we would respectfully like to comment on this guest’s review and experience. The alarm and subsequent events were unfortunate, and for their trouble the guests were offered a refund. Our guests had put baby wipes in the toilet, causing the septic system to back up. Thankfully, our septic alarm went off, and in mistakenly assuming this was the security alarm, the guests unintentionally armed the system, causing a visit from the police. We were unavailable for the first 30 minutes of this unfortunate incident, after which we disarmed the system and had emergency service to repair the damaged septic system. As far as the comments about cleanliness, the house was, as always, professionally cleaned prior to guest arrival, so I can only assume we have a different set of expectations of cleanliness. We have enjoyed meeting and hosting our guests on Airbnb, and we found this experience very dispiriting. We look forward, however, to more positive experiences in the future!
