uncomfortable message and booking how to cancel what to do

I received a booking with this message, I dont feel comfortable hosting this person and asked to cancel, I cant find a way of canceling myself, it was a last minute booking , looks like spam or what the ??????

here the message, apparently the fee has been paid, its a confirmed booking 

your getaway retreat has been recommended very highly by my Psychotherapist, this is a major step for me, i have just lost my husband, 4 children, 2 grandchildren, my job, my home, my family & friends so this i feel is the perfect adventure to not only grieve but to get back in touch with nature and my self. do i have a refridgarator in my bus? is it possible to have access to a microwave please? does my bus have air conditioning?
