Matt's place was like going over to your younger brother's house when he isn't expecting company.
The sheet on the bed was dirty and there was no top sheet. There were shoes everywhere, dirty dishes in the sink, dust on nearly every surface, hairballs on the floor, un-flushed urine in the toilet when we walked in, and there wasn't toilet paper in the bathroom on the main floor. We chose to wear our shoes inside because when we walked around with socks or bare feet, we had hairballs, dirt, and filth accumulate on the bottoms of our feet. Thankfully, we had our backpacking gear with us so we slept on top of the bed in our sleeping bags.
Matt was unavailable and had appointed his roommate, "JJ", as the main point of contact for our stay. She did a good job checking us in, but when I confronted her about the disparity in our expectations vs how our experience was going, she chose to lie about putting clean sheets on the bed and spending hours tidying up. When I called her out for not telling the truth, she proceeded to dismiss any responsibility by stating that she is a very busy professional.
As guests (and as a host myself), we were very disappointed with our experience renting Matt's room. He seems like a nice guy, but we had a terrible experience with JJ and the state of the home.
