Host changed the reservation last minute - normally not a problem. But as a result, I was not provided the correct gate code to enter the property and did not know this until I arrived late at night. I had to climb the gate to get in as the host was unreachable.
Property has some type of mildew/moisture issues as evidenced by rust on metal surfaces (stainless steel trash can, bathroom door hinges, closet door rails) and residue around AC vents. Wasn't able to breathe that night and didn't realize these issues until the following morning under the light of day.
On mentioning this to the host, he adamantly denied that there was any moisture issue. He then tried to make me change the reservation to be just one night to reduce the cost he would be liable for in terms of a refund; when I refused, he then stated a refund wouldn't be issued. He then went on to state that I had made a "false claim" and would be responsible for any costs associated with a "mold investigation." Dishonest.
