Can I change the house I want to stay in once I have already booked?

Sometimes.

Once we have reserved a specific property for you, any change that you might want to make is subject to availability.

In addition, in order to switch your villa of choice to an alternate one, we would have to be able to re-book the first house to another guest so as not to cause financial loss to the homeowner, on whose behalf we have already confirmed a booking for your specific dates.

If and when those parameters are met, any change in rate from your original villa choice to your new choice would have to be collected in order to guarantee the new booking.
