Bug issue, had to cancel halfway through stay. Host took no responsibility.
My husband and I found maggots (termite/cupim) halfway through our trip. The maggots were coming from the inside of the wooden closet and laying eggs and crawling in our clean clothes.
We immediately notified the host, who admitted that the issue was recurrent but took very little accountability. We agreed to move to a new place, without a balcony or pool, and farther away from the beach (to stay within our original budget) and asked the host to cover only the price difference and laundry/moving costs.
After a lot of back and forth, we were forced to move to a different Airbnb, and pay MORE out of our pockets for the new place and laundry costs.
Even before the bug issue, the apartment was very damp/smelled of mold, and missing basic items, such as toilet paper. I use Airbnb often and have never encountered a worse situation than this.
