The stay started well enough, with the owner meeting us at the MRT station and took us to the house, which was necessary as we wouldn't be able to find it on our own. There was a very lengthy check-in, the owner going through every small thing, which was our first evidence that he is overly protective of the house and paranoid about what anyone might do to the place. We then went out to get food and when we came back with the A/C off we then really smelt it -- the mold. We searched for the source, and after looking in the built in storage under the seating area by the dining room table we found it. We have had mold problems before and we recognized the full extent of the damage. It had spread and eaten through the entire seating area and cabinet by the rear windows. The owners were definitely aware of it, as they moved some of their items from one cabinet that had turned fully green and black. The other cabinets also had the same strong smell and large amounts of staining indicating the boards under the laminate were fully soaked with it. We also saw the many bugs and crittrs living in each cabinet that thrive on the mold. My wife, daughter and I over the course of the night felt scratchiness in our throats. My wife is very sensitive and felt it also in her chest and became lethargic and stayed in bed the next day, which was very unusual for her. We told the owners and they did come that day and wiped the area down with alcohol. This was of course fully inadequate and essentially had no effect as it had penetrated through the furniture itself. I tried further cleaning that night and had nothing to show for it but a really bad throat. From our experience, the only solution was a full rip out and replacement of the built-in storage. The place was unlivable and we asked the owner to come by the next day as we planned to move out and wanted to know if he could provide another place. In this situation we expected a refund of at least the unused days or another place to stay, as it was very clear the extent of the damage and the serious health risk the mold poses. After a very heated discussion, the owner agreed only to a partial refund of the unused days, he didn't have another place, and we were out of pocket for a large amount and had to move and find a new place. As we had prepaid there was not much we could do about it. We told him we needed to book a new place and pack up and that we would text him know when we were ready to leave -- this was about 10:30 am. This was where it got really weird as the owner came less than an hour later...
