@Audrius0 It all depends what is the cancellation policy of the host with who you booked. If it is strict for example you may get only 50% refund if you cancelled 7days before your booking but if you cancelled less than 7days before the date that you were suppose to arrive you will not be refunded at all. Check the policy of your host and good luck!!!
As @Oomesh-Kumarsingh0 has said, it depends on the cancellation policy of the host. Here's some information that I was able to find in the Help Center in case you'd like to have an indication of the timeframe.
