I meant that it's not sustainable because it takes a lot of work to welcome the guests, clean the flat and sheets all the time. It gets to a full time job really quickly if you have a few flat, and they better be in the same building.

Also, the price is expensive for guests... but as host, AirBnb takes 20-30% commission and you don't get paid for empty times. There are lots of emptiness if you do short rents.
