Cash was excellent leading up to and for the beginning of our stay at the Airbnb. She was very responsive and accommodating. Additionally, her cleaning service was excellent. Everything was in its place; sheets were changed, not a spec of dust anywhere, etc. However, there was an awful moldy smell throughout the house. Being the easy-going people my wife and I are, we didn't say/do anything because the place looked clean, and we hoped it was just due to the cleaning person using an old mop or something. We also left very soon after checking in because we had a day of activities planned. On our 2nd night there, we got the feeling that there must be something wrong within the floors or walls of the apartment. We looked all over the apartment and couldn't find any visual evidence of what was causing the smell. The moldy smell only got stronger and was nauseating at this point. We also had our 1 and 3-year-olds with us. For this reason, we decided that we didn't want to risk our kids' health, especially given their age and the possibility that the cause of the smell could harm them. To make a long story short, we contacted Airbnb to have them remediate the situation. Our request was to be refunded for our remaining five days and that we would eat the cost of the days we had slept there. Cash (the host) refused to refund our money, which was surprising to us given there were a 1 and 3-year-old staying there, and we assumed she wouldn't run the risk of their health and this situation blowing up into something worst. We ultimately left the Airbnb with no other place to go and still had five days left in Los Angeles. The bright side was that Airbnb ultimately helped us find another Airbnb and credited us some of the money using their insurance program. So do I recommend staying at this Airbnb? Not at this time, no way. Whatever is causing that smell is infrastructure-related and not something that goes away with cleaning. Also, I can't recommend this Airbnb based on how the host ultimately handled this for us. She could have refunded us the money for the days we didn't stay there.
