Changing your mind is not an "end of the world scenario", but it implies a whole lot of possible problems on our side, so please don't jump into the process light heartedly.
We don't guarantee that it can be done, but we'll do our best to ease things out.
If you have booked only a few hours ago and some other option is available it's almost sure you'll be relocated.
If we have kept the calendar of the "original home" closed to other bookers for weeks, and/or the owner has been paid before hand for the rental, it will get a pretty steep path to climb. Houses don't belong to us but to single private owners, and once we've processed the payment to them there's no way to take the money back out of their pockets.
If you've booked directly though us, there's no actions you need to take other than letting us know.
If you've booked through Airbnb or other portals such as Booking.com, you'll need to cancel or modify your booking through their website (letting us know before hand, so we can agree on the price and close off the calendar of the "new home").
