I live in Amsterdam where there’s a lot of AirBNB and I see and hear two big negative consequences: (1) rent and house prices have gone up because people can make more money with AirBNB than regular renters and houses being bought as investments. (2) I know some people in the center of Amsterdam that see (before the pandemic anyway) a lot of trash on the streets (discarded mattresses) from “homes” that are being AirBNB’ed. And lots of noise complaints as well.
