That was my worst in Airbnb.
Dirty floors and furniture.
Stinky dishes.
Old and disgusting smell bed linen.
No heating in one of the room, in another it's only gas heating in the kitchen, you'll smell gas every day. Only mattress is in the bedroom, no bed. It's blown on the floor from an old windows and the small heater is not enough, it's cold every night there too.
Problems with a hot water. It's switching off cause of the lack of pressure (10th floor). Very annoying and inconvenient. There is no info about that.
Insects, geckos and spiders. We killed 3 spiders, on the 10th floor in the city.
Hosts smoked just before our arrival, there was an ash in ashtray in the kitchen. Host wasn't friendly and told us that everything old here and if we broken it, for example a washing machine, that will bi our problems.
After we told about problems, host suggest us to cancel reservation and give us the rest money back. We agreed. But in fact, she didn't do that and ask us to do that by ourselves through Airbnb. If we would did that we lost 100% of the money rest, due to hosts policy of cancellation. That was the first time. The second time they lied us was when Tadeo, the son of the host (actual host is not Tadeo, but his mother) told us that he could give us money back if we ask for that through Airbnb. We asked, but he didn't agreed. We had a conversation here in Airbnb with a support member.
