The host was extremely lovely, even showed us around the area which he knew really well. Unfortunately, the accommodation was really unclean, sticky floors, half washed kitchen utensils, a hair caked bedroom carpet upstairs. In our deep cleaning of the apartment, we found a scary amount of black mold that the host had known about before we arrived and I think hoped we wouldn't notice. He eventually offered to have it professionally cleaned, but there's no scientific data to back up that fumigating the mold actually works and there was enough mold that it didn't feel like an adequate solution.
Considering that the host knew about the mold before we arrived, chose not to alert us or deal with the issue and has not offered any sort of additional refund or compensation for knowingly putting us in an unhealthy and unsafe accommodation has left a pretty sour taste.
Again, Chris was initially lovely, and if you trust mold fumigation it's probably a fine place to stay by now.
