Roaches, noise restrictions, and an awkward layout.
The house was infested with cockroaches. After we informed the host of why we left right after checking in, he told us that roaches are unavoidable in Sydney and that other guests left highly rated reviews of his property because they had their "expectations set correctly."
Outside of the roach issue, we had other concerns as well. Just prior to check-in, we were informed of additional house rules to include alcohol and noise restrictions in the evening. We were also informed that the house is monitored by "noise sensors" throughout the property which notify the host if the sound level exceeds a certain decibel level.
Admittedly this is subjective, but the house was not at all what we expected based on the lavish description in the ad. The bathrooms are in random/inconvenient locations and there is no group dining table/area inside the house. In my opinion, the host was quite generous in his written description of this property.
