Thanks for your answer.
I would like to stay in this place because it looks really nice (that's why I book it) but the representant of the host is now telling me that if I don't agree on the change of price, then she will cancel my booking and I can look for another place. Is that possible?
I feel a bit trapped meaning I have to pay more if I want to stay in the place I originally booked and I don't really want to look for another place.
The representant of the host says the mistake comes from the system on the website...
What is then my right as a customer on Airbnb? I don't feel like the reason of the host is legitimate.
Thanks a lot
