Response from J&B:
No, we're sorry for that post, but that's not true, so don't get afraid. We tried to contacted the guest (as we do it everytime) some days in advance /several times) and we tried to call her when she didn't show up a lot of times. She never wrote back or tried to call here and also, she didn't came up to our house (she had the adress). After some days she wanted her money back- because she has never been out of America or sth. like that.
We had no troubles in 2 years hosting like that and hopefully we don't get another bad intention- guest like that again. Ben & Jana.
