Always take a close look and careful read the cancellation politics for the hosts and also for the site, as no one book a stay thinking about canceling it sometimes there are strong reasons to cancel a trip, but there are some persons in the site that will not refund you a dime no matter what happen. I lost USD 700 with this BicycleJoe when my Mother got sick and I have to cancel my trip to NYC over night, he share his condolences but did not refund me a penny because of his own personal booking politics and because the guy is jobless. The site didn´t help at all even whet the situation fell in their politics, I sent documents and ll stuff I had regarding my Mom´s health but was not enough for them to refund me. So next time read careful the politics but mainly the other travelers reviews. And ask your parents a prevision of when are they going to fall sick so you don´t book any trip. :P
