We stayed at Felicity's home for less than 12 hours even though we initially booked for 3 nights. It is not the cleanest/newest house on the block, but accurately portrayed in pictures. However, cleanliness was not the problem we had with the house. The reason we left was because we discovered carbon monoxide readings of 54ppm, which is dangerous exposure over several hours. As a traveling family, we take along a portable battery operated monitor and it quickly picked up the reading. We gathered our belongings and left in the middle of the night with our 2 toddlers. Although the stay was not as we expected, I will add that Felicity was very quick with communication and asked how she could help as we were going through the ordeal. At the end of the day, we were quickly refunded for our booking without any issues. I hope that the host and Airbnb will work together to resolve the problem before the home is listed again.
