I had a late check in but kept the host posted of my arrival time. When I arrived, I could not get hold of him via numerous messages and phone calls. After an hour of waiting around, I had to make another plan to get alternative accommodation. The host phoned me only the next morning to ask where I am. He apologized and agreed on a refund afterwards but when I requested it formally, he apparently refused - which I found completely unacceptable from him. Fortunately Airbnb was excellent and resolved the matter for me, which I was extremely grateful for.
Therefore not a great experience with this host and an experience that should never repeat itself.
