Please leave the house the way you found it. That means don't trash the place and leave your mistakes on the carpet or walls. If you do, you should clean it up yourself. It's a house, not a hotel.
If you used the keys for the back entrance, please leave them in the entry way drawer (under the white lamp).
First the positives: the price was affordable for what we got. Host communicated in a timely manner. We were happy to be able to bring our pet. HOWEVER, the house did not smell or feel fresh. There was a lot of smoke and pet odor, as well as some deferred maintenance. Curtains and carpet were dirty, broken sinktop, and very few kitchen items. I would not say here again.
