I'm learning they are pretty common. I booked my stay months in advance. Then about 45 days from the time I'm set to leave I got a message from my host saying they can't host me the last week of my stay because they have family coming into town. So they changed the dates, so I now have the last 10 days of that part of my trip to find a place to stay. Before I accepted the new dates I sent a message to make sure that the rate per night would stay the same because they were the ones to cancel, I was sent a message saying I had booked at a discounted rate, and that the rate per night would go up, they proceeded to tell me that their neighborhood was worth a lot more especially for the time of year I need the accomodations. It went up a little but was still a fair deal and because every other place was booked up with in my time range I accepted. I am suppose to be refunded 380 dollars but I am now finding to fill those days because of deposits it's going to cost me over 1,000 dollars! Now I can see that my next accommodations I have booked with a different host, which backs up perfectly to the original dates I had booked of the first host has an opening. So I'm trying to push my stay up with that host, however I won't have money in my account for possibly two weeks, I'm finding out now, from the refund of the first host. I had read of cancellations and was afraid of that so I went with a "superhost" that title doesn't mean crap. You take a chance no matter what.
