be sure you know they will hold a deposit against your credit card, which is to back up any disputes between you and the host for damages made in their home. they can hold the deposit upto a period after check out.
furthermore, the host can suddenly withdraw from the rental without any liability due to eg. they sell the house etc. search more on Tripadvisor ,you will find some odd cases in the past. do more search, and comment. don\'t trust the picture.
good question! yes they can without liability. this was what I found happened on trip advisor. though not very often, but these do happen. lot more cases can be found on trip advisor as airbn has some history in overseas countries so many more user experience there on trip advisor. Just that it\'s business expands into Asia in these recent years.
