I have stayed in many airbnb's over the past 5 or so years and this was the worst stay ever. The first place had very unclean common areas, but with 5 people and someone's regular sleepover guest that was to be expected. What wasn't expected was an unsolicited incident with another guest that had to be reported to airbnb. The host was responsive in switching rooms to another house in the area, but that placed me far from where I was studying and became a major inconvenience in having to find alternate methods of transportation.
The second house was fine, though dirty, and one of the guests kept coming to me about bringing guests over to this new house instead of going to the host for permission. Again not a problem, but that guest was doing it to avoid notifying the host about what he wanted to do in the host's home. Fortunately I found a permanent home and was able to leave early and cancel the remaining stay.
Keep in mind the high turnover and host non- presence.
