I want to first say that Gary has been very gracious and responsive with my time at his place, and my experience seems to be a significant outlier compared to everyone else's 4-5 ratings.
I booked 11 nights but left after 2 for two reasons: 1) There is no working central heat in the home and was told to use two space heaters instead, which takes a few hours to warm up an entire house, and 2) there's actually a second unit attached to the house with tenants living full-time. This by itself isn't an issue, except that I was on the phone with my father and he asked, "What am I hearing?" And he was hearing the neighbors behind a wall and through the vent having a heated conversation that lasted 2 hours until 11:20pm. At this point I messaged Gary and told him I'm going to have to find something else, as I was expecting an entire house to myself, and would also expect working heat. Even though Gary did say he asked the tenants to quiet down so I could sleep, they only did so two hours after I initially contacted Gary. And to top it off, they were smoking and since the house is connected with vents, the smoke came into the main house and I ended up sleeping in the living room as the bedroom was too smokey.
As I said, Gary has been really great with communication around the entire experience and proactively refunded me when I said I was going to leave to find another place to stay, which is why I am rating the overall experience a 3, but just be aware that the house has no central heat and you have neighbors. Most people wouldn't probably care about this, but it wasn't what I was expecting or looking for.
