The website is great to find host all around the world. We have use it I think almost 20 times, the booking is easy, sometimes there is discount for a week stay, some useful filters (breakfast, kitchen, wifi...). Once our host ( not Airbnb) cancelled our stay in New York one week before we arrive, we were disapointed, but Airbnb was quick to give our money back, they even give us a 26€ voucher. You just have to be sure about the host, read the reviews, check if you are allowed to cancel and everything will be fine!
