I found this to be really inaccurate. I've been a host of an Airbnb for a few years. I've slowly moved my price up until I hit the maximum 70£/day. I have hundreds of positive reviews.
The price the website suggested was 120£.
I then went in to put an obscure address where there is no demand, and the price was $140/day. I've rented a hotel in the area for $30/day.
