We stayed at this rental Sept 23rd -Sept 26th. Upon checking in Friday night, we noticed a mothball smell. It was late and we were tired; we unloaded and went to find rooms to sleep in. There were three bedrooms on the main floor. Walking into the small middle bedroom (that opened to the backyard), we noticed a very strong smell. Personally, a house we owned had issues with rodents dying in the crawlspace and ductwork. This odor resembled that. We searched the room and found nothing but it smelled strongest from one of the walls. The room also had a strong chemical smell that we traced to a large Febreze plug in. The odor was so strong it also permeated a second bedroom adjacent to it. Given that it was late, we opened all the windows to air it out, emailed the owner that night and managed to find enough other beds to make do. In the morning we contacted the owner again to see what could be done – we didn’t feel like packing up and moving out since we had a short vacation and would be outside all day. The owner said they would send someone out to check the crawlspace. That night, coming back we again noticed the bedroom smell was really strong despite the windows being open all day. The owner indicated that the person did not find anything and they would give us some form of compensation. Given that we were in Flagstaff to be outdoors we decided to tough it out and not use the 2 smaller bedrooms (we had 5 people). We texted the owner photos of the bedroom wall. Sunday we left all windows open again during the day. Sunday, after talking again with the owner about this issue, they said verbally they would refund us some money and then compensate us for a future stay – and would email us details. Monday when we checked out the smell was very obvious. The mothball smell had faded. The owners gave us late check out which helped since we had a lot to pack. We went in to arrange the bed and it was nauseating. To be objective, the house appeared clean. The kitchen and bathrooms were well stocked. We were refunded the cleaning fee which was a small portion of the overall stay. We have been with many VRBO’s and we have not had such an experience as this before. On Saturday, Oct. 1st we received an e-mail from the owner. They wrote that they had taken some further actions with respect to the smell and the room seemed OK. They offered to compensate us for a future stay at the property which we will decline given the experience, and maybe look more to hotels.
