When we checked in, we immediately noticed a very strong odor throughout the home. The smell was overwhelming, even though a window had been left open. There were also plug in air fresheners in most rooms, which seemed to be an attempt to mask the odor. This led me to believe the owner may have been aware of the issue. I believe it may have been pet odor, but I can't say for sure. Unfortunately, it was so strong that we were unable to spend time in the home.The house also did not appear to have been cleaned thoroughly. The sheets on two of the three beds were dirty and had to be washed the night we arrived. Several surfaces felt grimy, and we had to wipe down the kitchen cabinet handles as well as the Nest thermostat.I do not typically leave negative reviews, but the odor was truly unbearable. I hope the host is able to address the issue and have the home properly cleaned. Overall, the house would benefit from a thorough deep cleaning.
