Th suite is situated on the first floor, and basically it's almost a basement. It's an old house so when people walked upstairs, it was very noisy. Regular walking was loud, but sometimes it felt like people were jumping, and sometimes it happened in the middle of the night.
But the most upsetting part was that we found mold in the shower. At first we thought it was just the color had changed between the tiles, but when we wiped over it, it came off. This is a SERIOUS health hazard.
Another really upsetting issue was that there were several mouse traps in the kitchen which means that the place has mice and we were not informed about this. At night my wife would wake up from gnawing/chewing sounds coming from inside the walls and she was so terrified she went to check the whole place so that the mice hadn't gotten into our luggage or food and especially to check up on our child in case the mice hadn't gotten into his sofa bed.
This was not a safe environment. If a place has mold and mice, they should not be operating as an Airb&b.
