I recently booked a rental for one week, in Mexico. As a guest we pay in full, in advance, in good faith, expecting to get a clean and safe rental. I checked in to the rental and when it was time to go to bed, I found the bed to be disgusting, filthy! I could not sleep in it. No sofa, I had to attempt to sleep on a small love seat. I emailed the host first thing the next morning and told her the situation and that I would be leaving. No response. I emailed a second time, I sent texts, and tried calling, no response. To date, I have not received a single communication from the host, nor has she responded to Airbnb's email. Now Airbnb tells me I am not entitled to a refund as I did not let the host know immediately that there was a problem. Is there any other recourse for a guest to get a refund?
